Adyen has some issues today that appear to be ongoing - https://status.adyen.com/. It would be nice if T212 had a similar page, or at least some status messages when something goes down. I had to switch payment methods to Google Pay to figure out the issue is probably because Adyen is the payment provider.
We appreciate the feedback @phans - thanks for sharing it.
On a side note, Adyen’s team is working to fix the issue you mentioned, and everything should return to normal soon.
