Hi, I'm new to Amazon and the lovely workflows and UX you have all been privileged to experience ;)

I'm attempting to "Add a variable Product" from the Inventory page (Create a listing with product variations, e.g. colours and sizes), but I'm faced with a lovely and very useful message in a red box with a red triangle and an exclamation mark, stating....."Invalid Access - You do not have permissions to view this page" .

I can list products individually, so the issue is related specifically to product variation listings.

Where do I focus on troubleshooting this issue? Clearly, as a seller, I have zero control over the workflow and permissions on this platform.

TIA.
