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.

N‌ice greetings

I observed a similar problem:

1. load some additional airports to the list
2. move a waypoint of the route
3. tap UNDO
4. Voila: the airports in the list are deleted!

It appears to me that only additional airports are deleted.
Departure and arrival airports remain in the list.

Wish a successful debugging!
