After downloading the complete DFS AIP there are all plates in my iPad and i can use it offline. When i do the download again and checking for updates, all the smaller airfilds are not there in offline mode and no longer shown in the list.
What happened?

Mhhhh... that's weird. Can't reproduce the error any more on any of my devices (all android). I swear that it was there yesterday at least on my mobile phone. Don't know what happened... for the time being everything works as expected...

I download "All" and "DFS German VFR AIP". When I want to update the plates, I do the Downloads again.
Then all the Plates from the Download "DFS German VFR AIP" are no longer on my device.

once again, this is what I do...

Now, when I go offline for 1 second or so,all plates are back and shown at the
Document Browser again !!???
