MSFS 2024 Marketplace? Is it open yet?

Anyone noticed that some aircraft that were initially available, have now disappeared from 2024. I had purchased the Mitsubishi MU-2 through the marketplace for 2020. It showed up in 2024, and I had a quick look at it tonight and took it for a short flight. But when I looked for it a short time later, it was no longer available in 2024. The V35 Bonanza is missing as well now, and I definitely flew that in 2024 a couple of days ago.

I am guessing they are pulling aircraft from 2024 for some reason. One of the problems with this steamed system is you just don’t know when they have moved the goalposts.
