New user RC switch issues

New user with Phantom 4 RTK multispectral attempting to start doing population counts. Connected with drone and going through checklist when is stops saying the RC switch needs to be on P not S. RC is on P already. Warning suggests using DJI GO 4 to reset but that app doesn’t support Phantom 4 multi. Any suggestions would be great…


The P4 MS is not supported for automated flight but I believe you can make thermal ortho maps with manual uploads.
