TestFlight submission error in “What to Test” – Case ID 102871415765

Hi everyone,

I’m getting this error in App Store Connect when submitting a build in TestFlight:

“There was an error processing your request. Please try again later.”

Case information:

  • Case ID: 102871415765
  • Contacted Apple Developer Support:

April 17, 2026 (GMT+7)

  • It has been 3–4 days with no response so far

Where it happens:

  • App Store Connect
  • During the “What to Test” step
  • The build is already processed and available

What I tried:

  • Retried several times
  • Switched browsers
  • Used Incognito mode
  • Logged out and back in
  • Simplified the “What to Test” text
  • Checked that the build is not expired

This issue has been blocking submission for several days now.

Has anyone experienced this recently? Is there any workaround, or should I upload a new build?

Thank you.
