SkyDemon is not able to get a connection to my Air Connect device.

I tried with several 4-digit keys to get a connection to the device but it ended up in "Connecting to device" and I never got a connection.

FYI I use SkyDemon for Android.

Lateron I tried it with an IPAD and a second Android device from my friends with SkyDemon and Flymap installed. It wasn't a problem at all for Flymap to get a connection to my Air Connect device in a matter of seconds and the traffic was shown on the map but SkyDemon was still not able to connect.

FYI, I use Air Connect 2018.06.06 with an 8-digit pass.
