"TroopTrack has stopped"

I just try to open the app in Android (both Google Pixel 2XL phone and Verizon Elipsis tablet) and I receive an error. Clicking on the app will open the initial screen, and then immediately there’s a pop-up “TroopTrack has stopped,” and then the app closes. I have had this problem ever since the Android app was made available - almost two years ago at this point. Is there a fix for this? Is it just not compatible with all Android products?
