Thank you for your quick answer!
I'm referring to the issue described in #2
I’m also on Xbox, and I was having the same issues with disappearing planes. Every time I restart the sim, the recently released Bonanza, Baron, and Starship would not be shown on the aircraft selection screen. If I go to My Library, they’re all there and enabled. If I first disable and then re-enable them, they show up in the selection screen. But they disappear again on the next startup. Downloading them makes them available, even after rebooting the sim.
State saving seems to be working for me (avionics selection, payload, whether the doors were left open), and my hobbs meters as well.
I'm not talking about the state serving (which seems to work within a single play session with multiple flights). But quitting and restarting the sim leads to same the annoying behavior:
the Bonanzas and Barons aren't available anymore in my aircraft selection
the fix is to disable and re-enable the bundle in my content manager
I can reproduce that issue on XBox and Geforce Now (which uses the PC version). As said: no other of my addons shows that issue (including the Black Square TBM-850 - also bought via the Marketplace).
I believe you, that this might be a problem of Asobo or MS, but for me as the end customer that is not distinguishable. I just bought a product from the official Marketplace which in parts doesn't work correctly.
As you most likely have more insights about the addon related procedures I would kindly ask you to bring that matter forward to your contact at Asobo so they can take a look (and fix it).
The planes themselves are just great and I truly enjoy all their details and features
