With all the new amazing HMD’s being added to the game like for the A10C and Gripen, it’s a bit sad to see that this issue has not been resolved or acknowledged in the “Known Bugs” of the dev server changelog post. HMD’s are a big part of top-tier sim and it’s been absent for the past 2-3 months for console players.
The issue effects both Playstation and Xbox, however it does not seem to effect PC.
There’s been bug reports since nearly 3 months ago and I made my own just now which includes a video of the issue. Below is one of the older reports along with mine

I hope the devs can look into this issue with the release of this update
