I'm unable to add a build to an External Testing group in TestFlight.
When I click "Add Build" on the group, select the build, fill in the
"What to Test" field, and click Submit for Review, I get:
"There was an error processing your request. Please try again later."
App: Glimpse Meet people (com.salarumer.glimpse)
Build: 1.0.0 (14), uploaded Jul 4 2026
Binary State: Validated
The build exists in the iOS builds list and is fully validated — the
error only occurs on the final "What to Test" submission step when
adding it to an external group.
The issue is not isolated to this app — I'm seeing the exact same error
on a separate app that is already published to the App Store. This rules
out a build or metadata issue on my end.
I've tried:
Approaching from both the group page (Add Build) and the build detail page
