TestFlight install fails with “The requested app is not available or doesn’t exist” after successful upload (Flutter app)

Hello,

I’m facing an issue installing my app from TestFlight on a physical iPhone device.

App & Environment

App: Desi Charades

Framework: Flutter

Distribution: TestFlight

Build status: Upload completed

Device: iPhone 7+

iOS version: 15.6

Tester type: Internal

Apple Developer Program: Paid account

Issue Description

After uploading a build successfully to App Store Connect and adding it to TestFlight, the app appears in TestFlight with the Install button.

However, when I tap Install, I receive the following error on the device:

“Could not install Desi Charades App. The requested app is not available or doesn’t exist.”

The build is visible in TestFlight, but installation fails immediately. Upload Warnings

During archive upload, App Store Connect shows the following warnings:

Upload Symbols Failed The archive did not include a dSYM for:

  • ffmpegkit.framework
  • libavcodec.framework
  • libavdevice.framework

The app uses ffmpeg-kit (Flutter plugin), which ships precompiled frameworks. Steps Already Checked

Build shows in TestFlight

Build added to test group

Tester is assigned correctly

Correct Apple ID signed in on device

Device restarted

Waited for processing to complete

App Store availability set to “All Countries or Regions”

Questions

Can missing dSYM files for ffmpeg-kit frameworks cause TestFlight install failures?

Are there additional TestFlight availability or processing checks that could cause this error?

Is this error related to TestFlight build propagation or caching on Apple’s side?

Any guidance on what could cause TestFlight to show the app but fail installation would be appreciated.

Thank you.
