Turns out it was permissions in the end. Bluetooth was the one I was missing, of all things.
The permissions I had to allow to get the app to work:
Internal Network connections
Bluetooth Serial Profile
Everything else is locked down. I still get the "GoogleMaps has attempted to open an external connection" message from my first post, but that's just a mild irritation.
