When I tried to disable other Tic/Mobvoi apps, I got up to the part where I could only Remove Upgrades. After I did that, the app disappeared from the apps list. However, the apps were still notifying me, so the apps were not disabled. I could not go into Settings to disable the apps because the apps did not appear in the list.
If you want to disable the apps via adb, try this:
adb shell pm list packages -e
This will give you a list of all enabled apps on your watch. Look for any app from mobvoi, and use the command in the first post to disable the app via adb.
