[Unable to tune radios A35K]

I know the issue is with ATC. The issue is only on the A350. I have tried the Inibuilds A320v2 at same airport with no issue. 

[Unable to tune radios A35K]

NO!!

The autotune works. If I click for example 1-Tune Heathrow Clearance on xxx.xx the radio tunes to xxx.xx but i get no response from Clearance.

I do get a response for ATIS comms.

I have tried on using  a different aircraft at the same airport and all comms work.

I can tune manually but if I select option 1 Tune Heathrow Clearance nothing changes. The Comm window remains the same.

ATIS will connect and hear ATIS info.

Very frustrating!!!!!

[Unable to tune radios A35K]

I am unable to tune any radios on A350-1000 MSFS2024. So unable to get IFR clearance.

Have restarted MSFS2024 and also tried different airports.
