Battery Doorbell Plus motion wont work anymore

Hy,I´ve purchased a video Doorbell Plus last week and it worked fine for about 3 days. It wont recognize Motion in 9 of 10 times. I feel like the problem started when i tried geofence which didnt work properly.I´ve tried:- removed Battery for 10 minutes- reboot via App- reconnected to Wifi- deleted the Doorbell and did a re-setup- tried different modes- motion frequency highest setting- motion sensivity highest setting- no privacy areas- tried different motion areas- activated snooze and deactivated itCamera has an RSSI
