Following the instructions in the app to get me setup it asks to scan my contacts. Then gets stuck with a little spinner that never ends (at least not for 40 mins). I tried restarting the app. I have restarted my phone. Reinstalled the app. Nothing seems to get it off the infinite spinner. Left for 2 hours now and no progress. 
This is on Android
if you tap the top right of the screen there’s an invisible skip button.
