I’ve trying to include some sub-dials for the California watch face, with no success. The sub-dials options appear to be inactive. Then, why does the app show the sub-dials option below the complications?
The sub dial top and bottom complications only work when you have the full screen watch face. They don’t appear on the circular version of the California watch face like in your screenshot. If you set complications on the full screen watch face the first five complications appear as inactive.
