rtmfp NetGroup.Neighbor.Connect issues

Hi, I am developing a mobile app for sharing files on local network using RTMFP and I noticed there is sometimes very long delay between NetGroup.Connect.Success and NetGroup.Neighbor.Connected events (so I can start an actual P2P communication).

Sometimes it takes a second and sometimes even minutes on the same network. I was not able to find any logic when a why this delay occurs.

After I finally receive Neighbor.Connect the posting is quick and stable.

Tested on ADL <-> Android and ADL <-> ADL (Windows 10).

So my question is - Is this a common issue and is there a way I can deal with it?

Thanks!
