Hi @Martins_Odins
Something that hasn’t been discussed yet: the Companion app requires that you give it permission to Location access in the OS settings. This permission allows the app to use the Bluetooth radio hardware so the app can “see” the trainer’s signals properly.
In Android 10 and older - allow permissions to “Locations.”
In Android 11 and newer - you should allow permissions to “Nearby Devices.”
Would you go into Android OS Settings > Apps > Companion > Permissions > Location and double check the settings?
iPhone / iPad users: Apple implements Bluetooth permissions for iOS apps in a very similar way. If you’ve googled your way to this thread - please follow these instructions on Apple’s support site
