For android phones we experience that permissions is not always set the right way.
For the digital key to work, you need to turn on location and bluetooth, AND give Orbit the permission to actually use them .
Change app permissions
On your phone, open the Settings app.
Tap Orbit. If you can't find it, tap See all apps. Then, choose Orbit.
If you allowed or denied any permissions for the app, you’ll find them here.
Tap Nearby devices (= bluetooth) , then choose Allow.
Tap Location, then Allow.
See in the pictures below:
Are you all set? Then try again. It might take a few seconds before the app to update the permissons if you changed them.
