I am at my wit's end with this watch this week. Worked fine for years and suddenly it has so many issues. So, the watch is completely up to date in terms of firmware. I noticed it hadn't transferred my acitivity from earlier this week from my watch to the iPhone MySports app, but figured I just didn't give it enough time to sync. Well, it wouldn't sync this morning's run either. First thought was I needed to update the app, activities still won't sync. I next tried deleting and reinstalling the app, that didn't work either. I tried "repairing" the watch, I entered the wrong pin accidentally but every time I tried thereafter it told me the pin was wrong when I know it was correct. I then tried going into the Bluetooth settings on my phone and "Forgetting the Device." It is STILL telling me the pin my watch displays for me to enter when I try to pair it with the phone is incorrect. I have no idea what to do. I've also tried restarting the phone and opening/closing the MySports app multiple times.
