There used to be an Ankihub section in the sidebar above “Saved Searches”. But that is missing now.
Should still be there, just underneath the AnkiHub section. Can you check for add-on updates? Are you running 2.1.56 Qt6?
If so, send a screenshot of your full browse screen here
It’s working now. I had to update some of my other addons. I guess something was interfering with the browse window
