Ok I'm so frustrated with this, have wasted hours of my life. Had to delete my phone Bluetooth pairings for another reason, which then stopped my Watch 5 Pro from working.
I reset the watch, tried to reconnect to the phone and it would not pair with the wearable app
I setup a spare phone, with the primary email account, and it paired fine (great!). At this point I:
1. Remove the watch from my Samsung Account, and BOTH google accounts I had setup
2. Reset the Watch from within the watch settings itself
3. Started the pairing procedure on my original/main phone
4. I COULD add one google account but then it immediately followed through with with the same screen to add a second google account, it would not take either. It errors out with "This account already exists on your device"
So It's clear there is still 'memory' of one of the accounts somewhere, even though they were definitely disconnected from the watch (within google account settings).
