Video casting connection problem

Hi, the projector has connectivity issues. I have tried several phones but with none if them I am able to cast the the videos, neither on Netflix nor other apps. I find the device built when connecting it always gives an error message.

Same problem for me. Can’t cast Airpplay. It indicates it is casting on the iPhone but the screen remains blank or has the control buttons on the screen tho no image/video.

Note that you cannot wireless cast copyrighted content. Please use the Netflix app preinstalled on the projector, or connect to the projector by cable to view your DRM content.

I am not able to cast anything on the device. It seems like the casting function is simply not working.
