No battery indicator or video

I flew a couple missions today. The first mission started ok and was running as expected (except for a second black video preview window). I ended up aborting after a few minutes due to high wind gusts.

Winds died down and I changed up the mission so it would run on a single battery. This time I took off and the video preview window was not showing and the battery was showing zero percent. I also aborted this mission after one leg. Better safe than sorry.

Return to home worked perfectly both times.

I am using the latest version on iPhone 7 and P4P.

Has anyone else experienced this? Thanks.

Yeah I flew two missions yesterday and on both of them a second black video preview window showed up. Missions flew fine - just annoying having a second window covering the flight path !
