The gear display in TPV has never worked for the Stages SB20 trainer on any apple device with apple silicon.

Tested devices: macbook pro M1 Max, iPhone 13 pro and apple tv 4k 2nd gen.

Error message in the log file is always the same, at least for the macbook pro and the iPhone, log files are not accessible for apple tv:

OS Thread - BLE error Error Domain=CBATTErrorDomain Code=3 "Writing is not permitted." UserInfo={NSLocalizedDescription=Writing is not permitted.}

Stages SB20 gear display works fine on Windows 11 tough.
