I have a Garmin Forerunner 245 music. I gave it to my friend around 6 months back and he connected the watch with his account. I have lost touch with him but it seems he forgot to disconnect the watch from his account.
Because of this I cannot see any wellness data i.e v02 max, number of steps, sleep tracking, etc on my garmin connect app. I want to disconnect his account from my watch. What are the ways I can achieve this. Since I am not in touch with him I don't have his account information.
