I started losing flight logs on the iOS app about 3 weeks ago, I took my P3 to Mallorca last week and all of the flights logs disappeared from the iOS device I used, and only 75% of them reappeared on my Android device I use for the Mavic.
In addition, I am not getting images in the flight log for the Mavic flights.
I was putting the issue down to the DJI cloud service not the app.
