The other night I was flying into KGSP and I could not get on the Unicom. I know it is a smaller airport, but anytime I open ATC, it said “No Frequency” when I was within GSP airspace and did not show once I landed either. Is this a bug or is there just no Unicom for GSP.
I’ve been having this issue as well, it would be great if someone noticed it 
I hope the devs can see this and acknowledge it…
I have tested it a couple of times and did not encounter any issues.
After taking off from KGMU, KGSP CTAF was available and working.
Which device (brand and model) is being used and which OS version is it running?
