I just found a bug in Timelapse settings. Framerate and resolution settings are not retained on power off. After restart, they get back to default 2,7k/25fps.

Al;ready a thread with DJI on this here - https://forum.dji.com/forum.php?mod=viewthread&tid=301489

Seems that I didn't search the forum thoroughly enough. Additionally, this thread is posted in wrong section. It can be removed actually...
