A feature has been removed from the Smartthings Connect app. in the release dated 25 Oct 2018. It looks like this release has been targeted specifically at phones rather than tablets
The feature, under Notifications -> Activity - was the ability to “Filter By” a device or devices.
I used this feature daily to quickly keep track of my pet remotely via a motion sensor. The feature was also useful in debugging But now I have to wade through all the reported activity to try and find the items that I want
So I want this feature restored. I cannot see how removing a feature can be art of a continuous improvement plan
