Hello,
I was using SayIntentions AI. I have updated my aircraft to the latest version. When receiving messages from CPDLC, pressing wilco does not acknowledge the instructions. Also, when I request for Pre Departure Clearance, pressing SEND does not transmit the message. Everything else work, I am able to ATC and receive messages from CPDLC. Also, it was working perfectly fine on the previous version. Thank you.
