Seem to be having a few problems with saving photos to the app during flight.

Everything is there on the SD card but can’t see to get them to save in the app

Cleared cache and old files from the app but no luck

So been messing and basically when the drone, remote and phone are connected up everything shows up in the app media section when you turn off the drone it disappears from the app

cheers in advance

Same for me with th Spark.

Newest firmware and software on everything.

Worked until about 1.5 weeks ago approx.

iPhone 6

Same for me with Mavic Air and Mavic 2 on iPhone X

Is there a resolution to this?  I am having the same problem - reported it as a bug.  The pictures are not being saved locally on the device (iPhone) in the App.  Pictures are there on the drone/SD card, but are not being downloaded to the phone.   Videos are saving to the phone, however, I have noticed that a few are missing as well.   Good news is that they are all saved on the SD card on the drone - just a bit of a pain to pull out the SD card and have to dload just to share them.  This is using the M2 Zoom and all the latest firmware and software updates on an iPhone X.
