@DTS Engineer (Albert), I’m still experiencing this issue and have submitted FB25217370 with the affected app IDs and reproduction details. Our original TestFlight builds expired unexpectedly soon after upload. Five replacement builds uploaded today, October 16, all processed successfully and show Testing with 90 days remaining, but all five fail to install with “The requested app is not available or doesn’t exist.” For Threadlight Atelier, the tester is confirmed Accepted and build 0.1 (2) is assigned to the internal testing group. Affected app IDs (all version 0.1, build 2): Threadlight Atelier: 6820303494 Tidecraft Town: 6820303699 Pocket Convoy: 6820293282 Relic Relay: 6820301889 Second Chance Workshop: 6820302668 Could you please help route FB25217370 to the TestFlight team investigating installation failures? Thank you.
