My Developer Program membership expired. In my developer account, I was promped to renew it. This has been done and a payment confirmation has been immediately received.
When I reopen my account the same message "Your Apple Developer Program membership has expired." appears. The same message also states "If you agreed to the Paid Applications Agreement, you’ll need to agree to it again after renewal in the Agreements, Tax and Banking section of App Store Connect." To be honest I am not sure what it is. In any case, if I go there it is empty.
Note that a few months ago I changed my account email. I am now logging in with my new email.
I've been using the Developer Program membership to codesin and validate an App which is not sold in the App Store.
