After years of working flawlessly, notarization stopped working for me. Yesterday It suddenly gave me "Team is not yet configured for notarization", I contacted developer support as advised by the eskimo (no answer yet) but upon trying again today I got the following:
Error: HTTP status code: 403. A required agreement is missing or has expired. This request requires an in-effect agreement that has not been signed or has expired. Ensure your team has signed the necessary legal agreements and that they are not expired.
I signed the agreement, everything looks clean and nice, no notifications about any agreement pending approval but I still get this error.
