You’re registering a watchface for the first time.
I recently released a watch face and started registration.
After registration, the installation was enabled on the watch, but disabled on the phone. What can I do in the Google Console to enable the installation on my phone as well?
Yes it is very hard and complex. In theory the distributor and author certificates should just replace GWS’s and it should run on device like before. I have to find out what the difference is but don’t have the time. Maybe over the holidays when it is less busy.
