I thoroughly enjoy taking Spherical panoramas with my MA2 and was happy to see the same function on my new Mini 2.
However, the final image in the DJI Fly app is only approx 1.4Mbytes (relatively low resolution 4096x2048) and does not seem to contain the necessary EXIf data for facebook to recognise as a spherical pano.
Even trying to share directly from the DJI fly app to facebook does not work. ( it works fine with the same app and my MA2)
Any ideas or is this just a bug at the moment?
( I have also tried saving as JPG+raw but just ended up with a folder full of the original images on the SD card and no way of stitching them on my mac)
It is very easy to use app Meta360 both iOS and Android, to save original plate photo into 360 photo. After that you can post this Meta360 generated photo to Facebook.
