Many users (newbies) write bad reviews or send messages to developers because they can't uninstall a watch face.
They don't know that they should first choose a different watch face using the watch menu before they try to uninstall using the Garmin Connect mobile app.
The error message shown on the app also doesn't help or point them to the right direction. It simply says "Unable to delete watch face".
Some of them even think we programmed this "feature" on purpose. It's pretty frustrating.
But their point of view is quite understandable: if they are able to install a watch face using only the app on their phone without touching their watches, they should also be able to uninstall it without touching their watches.
I'm sorry to say, fellows at Garmin, but this is bad engineering. It isn't users' fault or stupidity. And it isn't our fault either. So I have to conclude that it's your fault and I kindly ask you to find a solution.
I have two pretty simple suggestions:
1) improve the error message
2) if the watch face that the user is trying to uninstall is selected, automatically send a message to the watch to switch it to the first stock watch face (just as when a CIQ watch face crashes), and perform the uninstall.
