Thanks for taking the time to post. Can you clarify which portion of the app is not refreshing? Any screenshots you can share would also be helpful for troubleshooting.
Yes, I am noticing that as well. The app notifications are also inconsistent. Open Xfinity home app > select Activity > only old events Restart phone > open Xfinity home app > select Activity > refreshed event log
My iPhone7 app does not have a filter for only old events.
