I cannot spawn into any airport with any plane under Free Flight.  I just sit there watching the loading circle in the lower right corner and end up having to Escape out.  What gives?

I had that problem a couple days ago. I was playing around with the community folder and trying out addons when it happened. Cleaning it out seemed to have resolved the issue at the time. I can't tell you if it was the actual problem or not.

Thanks will give it a shot

Had the same problem today, loading circle. Changed server but same problem 

 I noticed that most of the third party airports causes this. They are loading and seem to be okey but freezes at some point. 

Therefore, I think 2020 compatible airports need to be updated for 2024.
