Plane I bought doesn't appear in de list of planes at Xbox.

Hi there! This is Virginia O.

I understand that you are experiencing issues playing the plane that you bought for FS 2020.

I apologize for the inconvenienced this has caused you. I will do my best to help you.

Kindly verify your game purchase to your account by checking your Order history here: account.microsoft.com > Order history.

Once you see the game there you should have the option to install it.

And then proceed with these steps:

For game add-ons and other DLC, the first place to check is in your library:

In My games & apps, highlight a game (but don't select it).

Press the Menu button  on your controller, and then select Manage game and add-ons.

Select the game tile, and then select each checkbox for which items you want to install.

Select Install, to confirm the installation.

Thank you for your cooperation.

i did a air drop job for trevor. i droped the packages from the plane. after i taxied the plane, i got out of the plane. even though the plane was in the hanger, i failed the mission because i abandoned the plane. it seems you must stay in the plane until
mission passed appears on screen. i didn't pull the plane in far enough. i thought once i got out of the plane, i would pass the mission.

I am having the same problem with the CJ4. I followed the progress of the achievement plane by plane (5% at a time) and the last plane on my list was the CJ4. I've done many flights with it but it doesn's seem to count since I still don't have Jack of all planes unlocked. Highly frustrating...

i was doing the mission with the guy where we drive the ATV's into the cargo plane so we can skydive with them. as i drove up the ramp i bump the the side of the plane going in. i rolled out to the runway and the ATV rolled into the cargo plane. the message
"get back on the ATV" appeared. i couldn't as the ATV was in the cargo plane as it was rolling down the landing strip. all i could do is the watch the cargo plane lift off with my ATV. so i failed the mission.

It's been a long while since I've played Warthunder since it's so twitchy trying to fly planes with an Xbox One controller. Have you checked the available planes list to see if the one included in the DLC pack is now available to you? The DLC may simply unlock the item in the planes list & then you have to acquire it from there.

Good luck!
