Alert: Your Amazon Pay legacy settings seem corrupted…

Seeing this on the top of my admin pages:

“Your Amazon Pay legacy settings seem corrupted. If you see issues processing legacy orders/subscriptions. Please follow the instructions in the Amazon Pay Settings to go through a recovery process. ”

I go to the URL it supplies and see nothing about a recovery process.

Not sure what to do, but even the Amazon Pay button has become UGLY with the new update.

Any feedback appreciated.
