LItchi installed with Mavic pro 1 does not work with Air 2 Sr?

Originally I downloaded Litchi to run my Mavic Pro 1 then I switched devices and bought an Air 2 Sr. Litchi opens and communicates with the Camera but cannot get my device to take off and track an established program. Thanks for your help everyone. Cordially

Welcome @PYG07 ,

Do you still have the DJI app running in the background when you try to take off?
If so, you must force stop it. I know the Air 2S uses the DJI Fly app instead of the Go 4.
