My mavic air is currently recording to the internal storage. Even though in the top right the settings clearly shows 120. FPS 1080, when I go to the editor it shows all the videos at 720p at 30fps. When I download them it’s the same. There is also another 120FPS 1080 box on the top right next to the first one but it has a red 45 degree line through it. Any ideas what’s going on?  

The cached filed in the editor of GO 4 app are always 720p as taken from the live feed to your device. You’ll need to download from the internal storage or Micro SD card to your Mac to edit in the actual resolution and frame rate.

I’ve tired that and the downloaded file is also in 30fps. It’s not 120 despite that being the actual capture setting. Also what is the red line going through the 120FPS 1080
UI component mean?

And I was previously able to playback the videos in slow motion but that doesn’t happen anymore. Like something changed.

Did you ever resolve this?  I'm seeing the same thing.  I transferred the clip off of the SD card to my mac and Premiere shows it as 30FPS.  I triple checked that it was recording in 1080p@120fps - Shutter Speed: 1/240
