The Apple Ultra change watch face did not work by touching the
middle of the watch screen after upgrading to version 10.
I could add watch faces from the iphone but not switch to another
face using the watch.
Rebooting the watch and the iphone did NOT help.
This is for the Watch 10 version of the watch software and 17.1.1
for the iphone SE.
However, I toggled the LEFT vs RIGHT wrist setting and then the
BUTTONS on the LEFT then back to right which flipped the image
on the watch upside down and then the watch change face started
working. Apple has a glitch in their watch software.
I could touch the middle of the watch face and the current face would
shrink and I could swipe left or right.
