Cameras don't function as advertised; several issues

I bought 2 floodlight cam pros, a solar spotlight camera and 1 doorbell camera which replaced the Ring cameras that I had. Non of the Eufy cameras work as advertised and don’t work well in comparison to the Ring cameras.

When a notification is received and you click on it, I receive a message that the video is not available. As a result you can’t see who’s on your property or talk to them using the camera.
The activity zone setting for the primary floodlight camera works only part of the day though it is set as my default setting.

The doorbell camera doesn’t record every time someone delivers a package. It mostly records when a person is walking away or not at all.

The other floodlight camera is set to human only but records video with nothing in the video
