Map is unusable on Android / Map is buggy on iOS

[maxammann]

Describe the bug

• Android:
  The map stays a lot of times white/light brownish (background color of the map style)
  Another issue is that part of the map is not responsible (see Map partly unresponsive after rotating the device maplibre/flutter-maplibre-gl#54) This bug is again happening.
  The Ehrenamtskarte as it is deployed in the store is less affected. The deployed Nürnberg-Pass app in the play store is unusable.

• iOS:
  1 out of 100 times the map stays black when opening the app.
  We suspect it is because the map failed to load the style.json because of network issues.

To Reproduce
Android:

• Start the app and only 1 out of 5 starts will render a usable map

Expected behavior
Map should display

@michael-markl I changed the milestone. The app is pretty much unusable on Android right now.

@maxammann Interestingly, it works (reasonably) stable on my phone, so it might relate to the Android Version.

You have an iphone?!

It's definitely Android as I updated in the issue above.

We still use the older maplibre: https://github.com/m0nac0/flutter-maplibre-gl/blob/main/android/build.gradle#L42
