I am trying to set up a watch 4 on my mum's S21 FE, for some reason after selecting her google account that she is already signed into on her phone, the wearable app then opens google play services and prompts her to log into a google account again. An error then occurs saying 'this account already exists on your device'.
I have tried clearing google play services data and cache, and uninstalling and reinstalling the wearable app to begin the set up again, but the same problem is happening.
Can anyone suggest a fix?
