Yes I have. And not only watchfaces, but all CIQ add-ons lost config function. All Garmin Connect after update looks like a huge mess. Config functionality, notification and vibration ..., and I wonder what will be next?
[Edit]Looks like this is know problem on developers forum. They have reported it to Garmin so we have to wait for a fix.
[Edit 2]Problem seems to be fixed. CIQ add-ons have config function active again.
