Just updated to 1.7.2, I had to refresh credentials and re-sync - everything seems to be working in Smart Things but in the connected app I can no longer open the Status page for any of my devices
The status page should still be there, but there might be new security policies/restrictions on app side that block a non-secure web view from opening in the app.
Are you on iOS or Android? Please post a screenshot of the error/problem.
