In the middle of a run the audio prompts stopped working between 2 successive laps and have been gone ever since.
I'm using Garmin Connect 5.2 and have tried with most previous versions since 4.60. Also tried various degrees of resetting, pairing, un-pairing etc.
Music is connected via BT headset and playing on an Android 10.
It's crazy how Garmin can release those firmware updates without proper regression testing. It's even more crazy how there's no way to downgrade a firmware on a FR255.
