My app has never been associated with my personal Apple ID - this is exactly why I use a Business/Managed Apple ID for all development‑related work. However, after the most recent apple updates, TestFlight has started creating conflicts between these accounts. Current situation: The App Store is correctly linked to my personal Apple ID, as expected. TestFlight, which should be tied to our Business/Managed Apple ID for internal testing, is now incorrectly linked to my personal Apple ID. App Store Connect and our developer account remain correctly associated with the Business/Managed Apple ID. I should not be required to sign out of my personal Apple ID on the device just to use TestFlight with the Business/Managed Apple ID. This has never been required before, and signing out risks data loss if a full backup hasn’t been done. Attempting to switch accounts inside TestFlight results in an “internal error,” making it impossible to redeem TestFlight codes or continue our testing workflow. I’ve already tried deleting our app, deleting and reinstalling TestFlight and removing all personal email accounts associated with Apple Developer. TestFlight still forces the personal Apple ID. If anyone has any recommendations other than signing out of my personal account, I would really appreciate it. Thank you!

I’m hitting a persistent conflict between my Business (Managed) Apple ID and my personal Apple ID when trying to use TestFlight. My Business ID is correctly tied to App Store Connect, but the device always forces TestFlight to associate with my personal Apple ID. When I try to “Review” the Business ID in the App Store, I get the endless loop: “This Apple ID has not been used in the iTunes Store.” The review flow never completes. What I’ve already confirmed: Business/Managed Apple IDs cannot be activated for the App Store -Signing out of Media & Purchases doesn’t fix it -Tried on multiple devices - sign out - same behaviour -TestFlight still forces a personal Apple ID login even when everything else is configured correctly This looks like a reproducible conflict introduced by recent Apple updates, and it’s affecting Managed/Business Apple IDs across the board. Developer Support hasn’t provided a single actionable response despite multiple tickets which is unacceptable for a paid service. Has anyone found a reliable workaround solution for this problem ? THANK YOU in advance !!
