There's a photo to show what I'm talking about (to clarify, the navigation tab circled in red should be on the top-right, above the chat panel). Not sure what's causing it -- haven't added any new extensions and it was working as normal just a few days ago. I've tried: running in incognito mode, disabling all extensions, disabling beta features. None of these have resolved the issue. Using another browser seems to work, but I'd rather not have to resort to that. Any help would be appreciated, thanks.
