Like everyone else, I have connection problems. But my problem seems different. I do not get any warnings or errors. The connection just fails silently, and when I open GCM, the two icons in the upper right corner are fully grey. No green dot in the watch icon, and no blue arrows in the refresh icon.
Stopping and starting Bluetooth on the phone makes no difference. (Except on second though I think I do get the red dot on the first icon while BT is stopped, so the icons are not completely "passive").
If I close the app by force, by double-clicking the Home button and then swiping the app up, I can then restart the app and the connection will be fine.
I am using an iPhone 7 with IOS 13.3. The GCM app is version 4.25.2. Watch is running firmware 10.0.0.0.
The icons I am referring to are the ones marked with purple below:
