I have a GW 6 Classic. Over the years I created custom watch faces using WatchMaker to show my CGM blood glucose values, and with a graph. After the UI8 update my watch face disappeared from the watch. The WatchMaker companion app will not load on the watch, although it is listed in the apps list. I try sending my watch faces to the watch, but it fails. FYI, I have multiple scripts to run the functions, and used Tasker Project to set up the values.
I have reset the watch twice, tried to clear the cache, tried to reload the companion app after deleting it, all to no avail.
I can still get my readings on my phone, but it is inconvenient to pull out my phone and turn it on multiple times (especially when exercising).
