Hi everyone,
My app is already published on the App Store and works normally in production.
I recently created a new version in Thunkable where I added multi-language support (Portuguese and English). I generated a new iOS build and uploaded it to TestFlight.
The build installs correctly, but when I open the app through TestFlight I get this message:
“App Unavailable”
Error: ERR-665275
If I close the error message, the app opens and works normally.
This problem started only after I added the multi-language logic. The previous published version does not have this issue.
Has anyone seen this error before in a Thunkable iOS build? Could this be related to the new language logic, startup navigation, or some TestFlight/App Store configuration?
Thanks!
