@reolink-lorenz I've updated to the latest firmware on my NVR as suggested. This update now gives the 'Quick Reply' option on my Doorbell POE camera, but the NVR firmware update removed the camera info tab on the client app, and I'm not able to update the firmware of my camera's now from my client app as it says the file is an incorrect format even though it is the .PAK file downloaded for that camera.
