Smartthings and Life360 add user

My wife’s iPhone stopped showing if she was away or present at our house. She was always away. I removed her iPhone from all WebCore Pistons and I’m trying to add her back in Life360 smartapp in smartthings. It see her but when I go to save it it tells me the following, Device still in use. Remove from any smartapps or dashboards and try again.

How do I get around this…

Thanks in advance for help on this issue.
