ForeverGOS To be honest I am unsure what does @de0u exactly mean. I went to bluetooth, clicked on the watch > forget.
To be honest, I'm not sure what I meant either! I looked around a bit and so far have not found the post I remember reading, and, again, I don't have one of these devices. So I guess I am suggesting telling the phone to forget the pairing with the watch, telling the watch to forget the pairing with the phone, and, if there is a way to tell any cloud account to remove the watch from the account, doing that as well. But please understand that this is very-low-quality advice.
