Hi and welcome to the community. :slightly_smiling_face:

The post below was from Brave support staff (moderator) in a different topic. But it made me wonder if this may be your problem also.

If you do not have access to the “Hamburger menu”, you can go to brave://settings/appearance and try adjusting zoom there. Hope this helps!
