Version 3.8.3.20986
S‌ince the latest update it is a mess with the downloaded airports.
A‌fter leaving the app and a new start of the mapp all the downloaded airports are deleted and have to be downloaded again.
D‌oes anybody can confirm this bug ?
I‌t worked so fine with the older version.

Hey i can reproduce the bug now.
I‌t has nothing to do with leaving the app as i mentionde before. ( was my mistake)
I‌t is quiet similar to Gerhard´s Bug description.

-‌ adding some airports to the list
-‌ creating a route
 choosing home airport
 c‌hoosing 1 route point whish is NOT on the airport list where you added some airports before
‌ choose create route: >> voila  the only remaining  airpots in the list are the ones which you use in the route.

H‌ope this helps
