I'm trying to setup a new Galaxy Watch 4 Classic on my wife's new Flip 4. The phone finds the watch fine, goes through the agreements, Google sign in, and then gets stuck on 4 spinning dots indefinitely. Watch continues to say "Check your phone to complete setup". Bluetooth shows watch is paired.
So the problem ended up not being the watch or the app per se. After the setup screen saying "Retrieving your google account info", where it asks you to press continue to sign in to your Google account, there is a skip button in the bottom left corner. Push skip instead of continue. Problem solved. Watch still has my google account for play store, etc.
