Android App Crashes Connecting to Virb Ultra 30

Trying to connect VIRB on my Dell Venue 8 tablet, (Android 4.4.2), to my new Virb Ultra 30 mostly crashes immediately after opening the Remote Control screen, but before displaying what the camera sees. Or if it doesn't crash, it freezes and I have to kill the app.

Connecting from iPhone works without issues.

Any ideas.
