Ionic app crashes on iOS after a while

I installed my app on Android and iOS. On Android it works. On iOS, the first day, everything works fine. Then suddenly, the app stopped working. When I launch it, It crashes immediately. I opened settings and I listed all apps installed in my device. My app doesn’t appear. It looks like iOS has deleted it somehow. I removed iOS platform, updated plugins, added it again, compiled and build my app. It worked for a while then the same problem appeared.

cordova version: 9.0.0 (cordova-lib@9.0.1)

These reason probaply is that your app runs into some kind of scripting error, maybe try debugging it and check the console for errors :wink:

I have the same issue. Have you been able to resolve it?
