I'm looking for a compatible flight planning/automated flight app for the Air2s. I've tried airmap and a few others but they seem to not be working. Any suggestions you guys can give to point me in the right direction.

Hello there. Good day and thank you for these information you have posted. Since these are 3rd party application for the DJI Air 2S. I hope that you will get the best information with regards to this matter from our fellow DJI co pilots who have tried using the said  application. Just a reminder to please use the recommended DJI application ( DJI Fly application ) when flying your DJI Air 2S to ensure stability and comparability during flight and 3rd party applications can void the warranty of your DJI Air 2S. Thank you and safe flying always.

You wont find one yet as there is no SDK released for the Air2S.   And DJI developers said it was not going to be supported.   https://github.com/dji-sdk/Mobile-SDK-iOS/issues/456
