TestFlight build appears but will not install on device (“The requested app is not available or doesn’t exist”)

Hi everyone,

I’m preparing an updated version of my older game Plum Nut so I can eventually return it to the App Store. I’ve uploaded a new build (1.1 build 8) and it shows up correctly in TestFlight for beta testing.

However, when I try to install it on a supported device (iPad Pro 2020, iOS), I get this popup:

“Could not install Plum Nut. The requested app is not available or doesn’t exist.”

The build is processed and available in TestFlight, but installation always fails with this message. I have several games that install fine on TestFlight. This is the first and only case and time where I have encountered this.

Details: Platform: iOS Build: 1.1 (8) TestFlight status: Available for testing Issue first occurred: Nov 18, 2025

I contacted Apple Developer Support, but they directed me to the forums for technical guidance. If anyone has encountered this issue or has suggestions on what might cause it, I would be very grateful for any insight.

Thank you!
