Hi
We upgraded to Xamarin.Forms.Maps to version 5.0.0.2515 and Xamarin.Forms to version 5.0.0.2515
After the upgrade, the app crashes when a view is opened with map for Android versions < 9. Android version 9 and up works fine.
The error we get is
[DynamiteModule] Considering local module com.google.android.gms.maps_dynamite:0 and remote module com.google.android.gms.maps_dynamite:202414000
[DynamiteModule] Selected remote version of com.google.android.gms.maps_dynamite, version >= 202414000

I created a demo withXamarin.Forms 5.0.0.2515andXamarin.Forms.Maps 5.0.0.2515. Then I added<maps: Map x:Name="map" WidthRequest="200" HeightRequest="200" />for testing, it is working when I deploy it in the Android 8.1 emulator. -

@Bernhard Pollerspöck - I believe you are correct. Its when you add bind the positions. I have also attached a CallStack if that helps. -
