There are two issues:
1. Settings groups look and function differently between the sim and Connect IQ. In sim, groups are simply demarcated using a horizontal line while in Connect IQ each group is a sub-page. See attached pics.
2. In Connect IQ app, tapping on a group name opens a sub-page. On the sub-page the Save button seems to do nothing. When going back to main settings page, the Save button has disappeared.
Attached is a simple program that can be used to repro the issues.
This makes settings groups unusable
