Hello everyone, yesterday I made a flight between ZSSS and RKSI. When I was approaching Seoul I didn’t see any other aircraft and when I contacted approach no one responded it felt like I was doing a solo flight. Today I made a flight between KSLC and KDEN and there was ATC (ground and tower) I had no problem when I still didn’t take off ( i could see other aircraft and there wasn’t any problem with ATC). But right after take off, the same thing happened no traffic and no ATC. And also when I start a flight my device always crash.
I just wanted to report this issue and I hope someone can help, thank you.
