In my ongoing struggle with the MapFactor sdk I'be hit upon yet another problem. This time it appears that the fragment from the sdk holding the map can't render because it can't load the constraintlayout. I have a reference to androidx.constraintlayout:constraintlayout in main and I'm extending from androidx.appcompat.app.AppCompatActivity. Am I missing something obvious here? It feels like it shouldn't be this difficult.
Any hints or guidance on how I can solve this would be greatly appreciated
