Galaxy A 10 e updated to Android 10 OS. After the update TR app does not recognize Bluetooth. The phone recognizes other BT devices but the app does not. The trainer is a 2019 or 2020 Wahoo Kickr core
You mentioned that location services are enabled, but was the TrainerRoad application explicitly given location permissions? This is a requirement for Bluetooth to work in newer Android versions.
Thanks for the tip all the same. Working with the TR support team to figure it out. Hoping it gets fixed cause he just finished a base training plan and is eager to begin the next phase!
