Recently, I've started having the issue of no video (but does have audio) when trying to playback a clip in landscape mode. It plays back fine in portrait, and in live view landscape. This happens with Guarding Vision, LaView connect and hikvision. However, it works fine in RCA security and EZVIS.
So what's the problem, you ask? The problem is that RCA and EZVIS seem to have removed their sharing settings! So I can either view in landscape mode, or share the camera, but not both? I have looked everywhere, but no luck. Using 180726 firmware, android 8.
