in my published widget "IoTClient" one can save URLs via app settings.
This usually works pretty good.
But one user found a bug. If one tries to save a URL with more than one GET parameter, the iOS app saves the URL correctly to the watch but cuts the URL at the first ampercent (&) in the app settings view. If one saves a second time, the URL will be broken.

This problem does NOT exist if one uses the windows desktop version of the Garmin Connect App.
