Hi, I have been using P4P from last March an after last 2 updates , I have been encountering this strange problem. The video feed gets mirrored when camera is pointed towards Nadir. remember its the video feed and not the full app.  So, the biggest problem comes up is that sometimes I could not understand if it is moving towards me or away.

Am using android phones. Have checked with both Nougat (Xiomi Mi Max 2) and Oreo (Oneplus 5), but is facing the same problem. Does anyone know any solution?

You can try to refresh the firmware but if that does not fix it, then you may need to contact an admin to get the next beta firmware to hopefully fix the issue.
