Video Doorbell 2k poor AI in the last days/weeks

I dont know why, but the quality of the human detection AI has become sigificantly worse in the last days and/or weeks. Sometimes recordings are made cause of people bearly appear in further distance (20m on the walkway Outside my property) for 2-3 seconds, but e.g. parcel delivery man and newspaper carriers got filtered or not recorded at all, altough they put something down in 50cm distance to the doorbell.

Additional to that, the Count of filtered events in the statisics gone up through the ceiling.

Anybody else with that problem? Maybe the last Firmware-Update is a bit buggy?
