Amazon Changed Disbursement Schedule without Notifying

Amazon has always had us on a Friday to Friday disbursement schedule and since we use a bank on RTP network, we receive the funds as an ACH on Monday which is great since we can pay bills on Friday via vendor portals and those ACHs don't post until Monday after the Amazon disbursement funds are received. Any delay to the Amazon disbursement even 1 business day causes a 3 day loss of cash flow forcing us to make those vendor payments on Monday versus Friday (loss of 3 calendar days) and for businesses struggling, those 3 days are huge in terms of cash flow management.

That being said, I noticed Amazon did a mini disbursement for the period of Friday to Saturday 8/23-8/24 in what appeared to be their way of moving our disbursement back a day. Now for this current disbursement period, it is showing 8/24-present instead of 8/23-8/30 and I expect it will close later today. Amazon has in essence changed our schedule from a Friday to Friday to a Saturday to Saturday and they have not send us a single notification as to why. This probably benefits them since they don't have to send the funds until Monday instead of Friday so they gain 3 calendar days of cash flow on our backs but its very bad for us as we lose 3 days of cash flow at a time when our business can't afford it.

Is anyone having similar issues? Selling on Amazon seems like death by a thousand cuts. I feel like we're just lobsters in the tank with the temperature slowly rising. Maybe its just me but they continue to monetize their platform at our expense and that is why our business are suffering so much more than just what the poor economic conditions of this time are causing.
