Iphone 8 plus on IOS 15.6 with DJI Mini 2 - no video screen NOT BACKGROUND APPS

Totally removed DJI app and rebooted everything - no video presented. OK on DJI app

Completely shut down all other apps running in the background on your phone.

yup, not just DJI background but everything. If using the DJI SDK, why so? DJI Fly doesn’t require that.

I guess that’s logical if one assumes the added features of Litchi use more memory than does DJI Fly.
Thanks for your advice.

You will know the answer if you decode “sdk” - software development kit
