ATC offering wrong cruising altitude

I get my flight plans from Simbrief. I select the FP in PF3, and in MSFS 2020 by loading in both. The only thing I have to do then is set the Star waypoint to begin the star. ( I use a star on every approach so that I don’t have PF3 vectoring me). That’s it. Takes me 2 minutes at most to set up a flight. The Azure voices ( all two of them) are very nice, but I prefer the 100+ voice variety I get with PF3.

I use EFB to select my approach, and the advantage of that is EFB inputs into the GPS, the waypoints in the approach you are using, automatially. Once PF3 gives me the landing runway, I select the approach to the runway ( visual, LOC, or GPS) and EFB sends that to the GPS in the aircraft. Couldn’t be easier.
