This is fantastic. Many thanks for this, since I was at the point of resetting my watch and reinstalling from scratch, to try and get this to work.
As for the experience, I very much like the Wearable Widgets watch face using the G-Watch widget. It’s big and simple, but somehow, I don’t mind, since I can access all the other functions with swipes and presses. As for other watch faces, many of the digital ones allow complications, and I’ve tried a bunch, but dislike that the number is so small, since the BG number must fit within a small window.
