3840 × 2160 @ 60fps / 59.9fps doesn't work - sdk error

Hi,

I’m trying to set Litchi to use 4K/60fps (3840 × 2160 59.9… in the app settings) but whenever I select it, it gives me an error stating there is a SDK error and to contact support. 4k/60 works fine in the DJI Fly app for reference.

Drone is an Air 2S.

Is this a bug with Litchi and if so how do I report?

Cheers
