“testflight the requested app is not avaliable”

Hi, We are currently in the process of getting an custom iAP2 device communicating via USB-C. We have been using the 'EADemo' app as a test app to ensure full function before certification. Currently, the device completes the authentication and identification successfully. The device appears within the 'EADemo' app, and we are able to select it and see the available protocol. Selecting the protocol sends the EAStartSession command to the accessory and we ACK it. This is where the issues begin. Attempting to send either a string or hex packet results in nothing being sent. The app does not appear to attempt to send a packet when these are pressed. The 'EADemo' app also does not increment its receive counter when the accessory sends an EA packet, but we do receive the ACK from the device. This indicates the device is receiving the packet, but not processing it in app. Sending the EASessionStatus from the accessory with a status of

Starting today, we have been seeing this error message. This is a blocker for my team and any help is appreciated Things I've investigated: Testflight Apple status page is green Our signing certificate is valid/ unexpired Provisioning profile is valid/ unexpired There are no pending Apple account agreements Doesn't seem to matter if user also is a member of my company's Apple Business Manager developer team Cellular data is turned off Date/ time is correct User was unable to install app using a personal gmail account and unregistered device User was able to use Testflight to install a third-party app outside of our corporate account Uninstalling/ reinstalling Testflight didn't help

Same scenario described here: https://forums.developer.apple.com/forums/thread/738942 User clicked accept for an internal tester invitation sent to their work apple id on their personal device which was signed in with their personal apple id. This seems to have redeemed the code to the users personal account. However, the user has removed themselves from testing the app and we're trying to get their work apple id registered but the invite code that keeps being sent is coming back saying invalid. Things we've tried: We located the last build the user installed on their device and expired the builds deleted / readded the work apple id to internal testing group It's still sending the same invitation code from TestFlight and saying that the code cannot be redeemed.

‌Using Xcode 26, the built package encounters device compatibility issues — while it installs successfully on supported iPhone devices, but it crashes immediately upon launch and cannot run normally.‌‌In previous versions of Xcode, the same minimum deployment setting in the project did not cause such compatibility issues.‌ The app built with Xcode 26 shows the following behavior when installed and tested on various devices:‌ iPhone6p iOS12.5.8 fails to run 2.iPhone6 iOS11 fails to run 3.Iphone6 iOS12.5.7 fails to run 4.iPhone7 iOS12.1.3 ok 5.iPhoneX iOS 12.2 ok 6.iphone6s plus iOS10.3.1 ok 7.iphoneXS. iOS 12.1.4 ok 8.iPhone11 iOS 13.6.1 ok 9.iPhone7. iOS 13.7 ok We have tested and found that an iPhone 6s Plus running iOS 10.3.1 can normally run the app. We would like to know whether apps built with Xcode 26 are inherently incompatible with iPhone 6 and older devices. Has Xcode 26’s underlying build environment removed full support for the A8 chip, resulting in bina
