I posted this elsewhere but need support from other members seeing the same issue.
Please reply if you see this issue for the developers.

Syncing flights between devices still does not work.
Never has worked since DJI Fly's initial release.
For example, my flight device (iPad Air 3rd gen) shows my flight  tonight  as 18 minutes, 400 ft high and 4.77 miles traveled distance.
My backup device (iPhone Xr) using the same login account shows  1  minute, 170ft high and 39 ft traveled distance for the same flight.
  
Simply put, the log files are getting corrupt somewhere between the upload to DJI and the download from DJI.
When trying to sync with online logbook services, the same "shorter/ corrupt" flight logs are seen as well.


Here is a comment from an online service that sees the problem too:

Especially see the second to the last line in this notification.


Thanks in advance.

Agree.  This needs to be fixed.  Not sure how long ago AirData reported the issue to DJI but as usual the software developers are very, very slow to correct issues.  Would be a big plus if the flights would sync properly between devices.
