I have a new DJI Smart Controller for use with my DJI Mavic Air 2.
Latest firmware update ist installed and smart controller is well connected with the drone.
It has the DJI Fly App for controlling the Mavic Air 2 drone and also the DJI Go 4 App for the '@Go Share'-feature to download the files from smart controller to smartphone.

BUT:

The resolution of cached videos (resulting from auto synchronized videos from drone to controller) have 720p only.
If I use the original drone controller with DJI Fly App on smartphone, the resolution of such cahced files is 1080p.

(The settings of the videos at the dronme is 4k).

Is the DJI Smart controller limited and is not able to create larger video files?
The display resultion is physical 1920 x 1080.
Why are cahced files 720p only?
Or is there a special setting to modify the resolution of cahced video files?

Thank you for any tipp and help.

If DJI smart controller is limited to 720p I plan to send it back to DJI store.

I am new to DJI drones and would be interested in a solution to this issue as well.
It isn't even possible to run a screen capture on 1080p by use of third party software installed from the google play store because the DJI app terminates all of these capturing apps on startup.
This is not how I expected it to work...
