Just noticed that Lockheed Martin had released P3D v5.2 a few days ago.  Descriptions sound good with more than 100 new features and fixes and improvements.  https://www.prepar3d.com/news/announcements/2021/06/120786/

Hope this update solves the many issues reported before.

Lockheed Martin has finally released P3D v5.1.   Seems like not too many people are aware of it (based on the number of respondents in its support forum) while most people are keeping their eyes on MSFS — me the same.

Anyway, hope this update solves or at least improves the many issues reported after its launch.  There are still many features MSFS can’t or doesn’t do properly today.
