Galaxy Watch 4 - Could not add my Google account and Watch setup failed

[spartawis]

I re-install my galaxy wearable app because it bugs my phone to open persistently. This slows down my phone. 

As I restart my galaxy watch 4 and connecting it to my wearable app, it can't log in google account. It also fails every time the google is signed in and setup is about to finish (asking to restore my watch data from smartswitch). Also, encountering "Could not add my Google account".

As I am re-doing the restart on my phone and watch, it always fails. Please help me with my problem.

Factory reset your phone, then reset up and repair your watch to your phone?? Someone on here might know.

It helps for the meantime. I restarted my phone for the 2nd time, and it works for the 2nd time I connected it. However, logging in from wearable app seems the problem as restarting my phone and logging in was the part of the problem I encountered over again.
