I did submit via Feedback Assistant 10 days ago and it was resolved with "Investigation complete - Unable to diagnose with current information." - I'm not sure what more information is needed. The Feedback id is FB14788450. I included logs with an example of obtaining a successful transfer identifier and unsuccessful identifier exchange, timestamp, service ids, and also a CSV of all 60k failing users. There should be client secrets in the log file. I may need to regenerate since it's been so long. At this point we're halfway through the 60 day transfer period so any help would be appreciated.

Was this fixed? Just out of curiosity I ran my script yesterday to call the Apple API to transfer users, and we are seeing way less errors - now I only have 180 errors out of the 118k+ users I didn't receive any follow-up emails or messages on this - is it safe to now transfer the users and update the Apple ID in our database? I believe our 60 day deadline is Sunday September 22,2024 - will that be extended? For now I have saved all of the user information to a CSV file. If needed I can write a separate script to go through the CSV and update in our database
