Same issue. That thread you shared has no resolution just everyone asking when it’s going to be fixed, and that was over a month ago. I already filled out a ticket this morning. It’s been broken for nearly a week. I didn’t realize it was on apples end until today, I thought it was a misconfiguration on my end but it appears to be an Apple issue. It’s literally stopping me from releasing my app. I have a release party planned next weekend. Please let me know when apple plans on repairing this?

Been going on almost a week now. Ive also tried with CLI and it fails that too with same error.

Adding my details here as request from @DTS Engineer Its still doing it. I first noticed it March 1st but thought it was my configuration, after weeks of refactoring and trying differnent methods came across this thread as DTS directed me here. Adding my screenshot to the discussion.
