Hi Dave
Tried twice now with MSFS but request lower by 9000ft (L9) no longer works. The Co-Pilot now requests maintain current FL. For example at FL290 requesting FL200 the L9 key combo now produces 'TopSwiss 1151 requesting maintaining FL290' instead of the usual 'Requesting FL200. This morning LFSB-EKCH I got initial descent by ATC from FL370 to FL330 then nothing and so I called for lower. I got the above request from my Co-Pilot and an acknowledgement from ATC and then no further descent. I went down anyway and received nothing further until 'Proceed on the MONA2E arrival I'll have traffic for you' and then eventually the 'descend to 3,000 cleared for the ILS 04L. Everything worked fine after landing with taxy instructions to F5.
Logs attached
Cheers
Rob
