Hi,
Same problem here, after latest updates 1.4.1.1 for Airbus family and 1.0.3.1 for the A330.
I use pro atc and I have the "co-pilot handle com radio" function enabled, before these last updates, all worked fine, not that it doesn’t work now, i can fly quite good, but i have to put manually clearance frequency and then seems it works.
Never did before, as i have "copilot handle com radio" function enabled.
When I press "fly now" button in pro atc, before i unpaused the sim the freq shows up correctly (ex 120.45 khz for LIPZ TWR) , then, when i unpause the sim, the freq turn back for example to 128.225 KHZ, that there is something that swap the frequencies by do nothing.
I have a similar issue with the squawk, it swap by itself sometimes.
