Are you using Developer Mode or made changes in it?
No
Have you disabled/removed all your mods and addons?
No, this is an addon bug, wasn’t sure where to post this observation of the seeming bug I encountered today.
Brief description of the issue:
Black Square’s Cessna 208 Analog Gauge addon I experience trouble with Comm 2 “listening” or “monitoring” button whilst on Vatsim. I tried Comm 2 Monitoring in the default TBM 930 and it worked fine. For the Black Square Cessna 208 Analog Gauge, I am using the GNS 530/430 Radio configuration.
