Lovely. Apparently our app review instructions were outdated1 and now Apple cannot review the new submission. Recording a video late in the evening just to get this submission past the review. I could have used this time for something else.
Our app requires an authentication app as well for the reviewer to be able to log in. Now the authentication app's onboarding process requires an SMS-delivered one-time password, which is obviously not delivered to the reviewer but to someone else. A stupid change in another app's flow causes issues with our app…
