"The country of your Merchant Business Address does not, or has not, reflected your country of establishment" - UK and EU Disbursements Withheld and FBA inventory blocked

My UK and EU Amazon business in critical situation and it has been more than 1 month since my issue has not been resolved and did not get any reply from Amazon. I decided thus to start my own thread. I put here all the information I managed to gather so far, regarding this difficult type of issue currently affecting my seller account and a significant number of other sellers apparently.

My background as a seller on Amazon

• Been selling for 8 years on Amazon, as a sole trader, had multiple account re-verifications with no issues during these years confirming both my residential and business address is in my EU home country. I am registered in PAN-EU, use Avalara under Amazon VAT Services, I am VAT registered in the UK, my EU home country and all PAN-EU countries, I fulfill my VAT and tax obligations and I am tax compliant in all these countries where I am registered.

What happened?

• Starting with April 7th, I received multiple performance notifications on both UK and Germany marketplaces, all essentially asking me for the same information: " Confirmation of the country of establishment of your business".
• Since April 7th, my disbursements have been blocked and then later on, since April 19th, my UK and EU FBA inventory has been blocked for sale and removal.

PERFORMANCE NOTIFICATION TEXT:
<<To resolve the issue, please contact https://sellercentral.amazon.co.uk/help/hub/support/browse-GB-visa-filing-VISA-acronym and provide the following information

1. Confirmation of the country of establishment of your business - this is the country in which your legal entity is incorporated or you are resident if you are a private individual;
2. An explanation of why the country of your Merchant Business Address does not, or has not, reflected your country of establishment; https://sellercentral.amazon.de/sw/SSR/BusinessKYCInfo/spaDashboard/
3. Any documentary evidence supporting the above explanation.>>

What steps have I taken so far to address this issue?

• On April 13th, I opened my first case (ID: 8634962622 ) and provided the information I was requested basically confirming that my business address in the KYC page shows the correct country of establishment. This case is still in “Pending Amazon Action” status since April 13th. All subsequent cases we opened were merged together under the same.
• I have spoken with the Account Health Support using the “Call me now” button multiple times. They could not offer any help though with my case. They do not seem to know or have any information that can be helpful and recommend only to wait for further guidance from Amazon.
• on May 3rd, I opened a new escalation case (ID: 8690123172) to ASP360, a programe that I am currently enrolled in with Amazon

What I think is the cause of the issue
I contacted tax offices, in particular Germany and UK, to confirm there is no outstanding payments or a any other issues with my tax accounts. I read through other sellers’ posts dealing with the same issue. I double checked all the tax and KYC related info in my Amazon account.
From all this information I could gather, I believe this is most likely caused by a technical issue related to the Amazon KYC information for sellers who in the past had a change in the business address of their account from one country to a different country. This is what seems to be common among all sellers reporting this problem.
In my case, despite my information being verified successfully by Amazon in 2019, when I did my last business address change from UK to my EU home country, it appears somewhere in the backend of Amazon’s system the address change was not performed successfully, or in the right way. In the Business and Contact Information section everything shows as correct in my account KYC/Identity page and the correct country is seen at the begining as 2 letter country code, as it should. However, when I click on “Expand” button the country is not shown, and when I click on the dropdown it only shows “United Kingdom” as an option to select. This does not seem right, but it is nothing I have control over though.

What Amazon’s actions or replies have been so far
Using all the regular support channels, I have not received any information from Amazon since the start of the issue. Only “We are currently researching your issue in partnership with the responsible team and will provide an update as soon as any additional information becomes available.” and " No further action is required on your part" type of messages. Meanwhile our entire UK and EU Amazon business is dead: funds withheld, and FBA stocks blocked for sale and removal.

• from Seller Support - No helpful information or action provided so far
• from Account Health Support - No helpful information or action provided so far
• from Amazon Forum Moderators - I have read through all forum replies and could not find any helpful information

This seems to be the case with what other sellers are reporting too. With just 2 exceptions, none others seem to have received any meaningful communication from Amazon since this issue started. I have compiled below an alphabetically sorted list of all sellers I could find on the seller forums, reporting receiving the same performance notifications and dealing with some or all forms of account restrictions such as deactivation of account, funds withdrawal block or FBA Inventory block.
I really hope that someone from Amazon, that is actually in the position to help, will see this post and take action to fix this issue in a timely manner .
