I think I’m having a similar issue as you all.
I’m using the ATSimulations Piaggio.
I’ll take off, ATC is fine at all stages with the airport…
Then they’ll tell me it’s ok to switch frequencies.
I switch to Boston Center.
I ask for clearance through either Manchester Class C or Boston Class B
It tells me to squawk a channel
I switch the Transponder to that channel
poof, there’s no more ability to talk to ATC at all. All the blue bars for options disappear, and none of the keyboard commands for choices like “cancel flight following” work.
If I switch to a different channel, it suggests I tune back to Boston Center
If I go back to Boston Center, the screen goes blank of the blue bars, and all I can see is the discussion.
I have if I’ve flown long enough eventually gotten a blue bar which tells me to switch to a different Center channel, and it kind of works. Sometimes it disappears again after I make contact.
Communication with airports seems fine as long as I don’t ask for flight following.
this problem started immediately after the latest update.
I’ll have to test with a different plane to see if it’s related to the Piaggio.
