Today, I managed to apply the update successfully though, it was not tried differently than the other times when it failed. I wonder what is the deciding factor to succeed …
One thing I noted not matching to what is described in the changelog. I can only select between 3 options as Clock Face in the Settings, not 6: a) The default one with time and alarm time above, b) Time, alarm time above and battery below, and c) Hours and minutes stapled having an alarm icon aside.
