Hi @JP202,
Seems that this issue will require some help from support. You can submit a ticket here: Submit a Support Ticket.
Meanwhile you can try to investigate by yourself. You can have a look at app crash logs for iOS:
- Navigate to the Settings app.
- Tap Privacy & Security.
- Tap Analytics & Improvements.
- Tap Analytics Data.
- Select a crash log from the list in alphabetical order.
If you have Mac, you can share the crash log to it and then you can view its contents in a structured way. There might be some hints in the log, however, maybe you won’t find anything.
This thread is worth reading:
App immediately crashing from TestFlight.
As a side note: all the time when I saw app crashes, the app either ended on a white screen or closed immediately. I’ve never seen a black screen before. Maybe this is because of a screen background (??) or the app doesn’t crash but is simply stuck on some screen (??). Crash logs should help to indicate that.
Another thing what I would do - is to rebuild the signup screen and the following screen(s) from scratch, removing all extra components, and see if the app continues to crash. I see that you’re using Apple Sign-In and Google Sign-In - I would try removing them as well. Of course this should be a temporary testflight build and it will never go to production - you’re going to be doing it for testing.
Also it is quite strange that previous builds stopped working as well. If that could be proved, then logically thinking there is something changed either in iOS or in the backend, which now causes the app to crash. In the backend I can imagine some issues with the database (e.g. collections permissions? maybe you’re trying to write something to a user collection which doesn’t work?), or some settings in the Appstoreconnect/AppleDeveloper (certificates?), or some changes in the custom actions(?), or some other Adalo backend issue (maybe you’ve run out of actions or something like that?).
Sorry I can’t give you a recipe here, but hope these options can help you to explore the issue further and find the solution.
Best regards, Victor.
