After a Feb 2021 update I couldn't find it.
I tried to talk to samsung support but they wanted remote access which I denied.
Its blocked by the bottom bar.. i accidentally found it like 2 days ago..
I tried to screen record it.
Yep. I updated and restarted nothing worked . But I also just figured it out. Its back to normal.
For others that want to know:
If you go to your settings > display >navigation bar and switch to hide the bottom display then switch back (I like the buttons to show) it fixes the issue.
