How many of you are old enough to remember being told to Ctrl-Alt-Del to fix a problem? Well, it’s time to relive that memory!
Issue #1, where the app was not remembering the the GUID is fixed with a “cold start” of the watch with a long press of both buttons till it switches off, then restart the watch with a press of the left button.
After a couple of frustrating days trying to find the problem in my code (that was never there), I have concluded that the watch’s operating system was knotted up somehow and the restart cleared the problem.
It explains why we hadn’t experienced the problem before, because it’s such an unusual condition.
So If the app refuses to run without being connected to your phone with an internet connection, please try this “cold start” procedure described above.
