DJI P4 Multispectral NDVI workflow

I shot a test mission with a DJI P4 Multispectral.  I used DJI GSP since the P4 multispectral isn't listed as compatible with Map Pilot Pro.  I'm using the images directly from the drone's memory card.  I'm trying to figure out the right way to process with Maps Made Easy.  I tried the DJI workflow, but I got an error message.  When I try to upload the test photo, I can use a RGB .jpeg, but the .tif files created by the drone are not selectable.  When I try and do the classic workflow, same issue.  I read that the flatmap processing will work for thermal.  Will it work for NDVI?  Previously, I tried converting the .tif files to .jpeg, but then MME gave me error message that the metadata had been altered on those images.  I couldn't find a workflow on this on the website.  Do you have one?
