Beginning about 01 January 2021 the trigger history for almost all my contact and motion sensors is blank, as the App returns the message “No Records”. This is particularly the case for sensors organized in groups. All these sensors in groups trigger properly and show their status when triggered but there is no history of the individual trigger events for any of them. Most of the sensors not assigned to a group do show their history.
Several other posts about this…no fix as yet.
