Ok thanks! I pushed an update (1.0.85) which possibly fixes this but I wasn't able to recreate it locally so I'm not exactly sure. I suspect it has something to do with filters..
Thanks for the bug report! I'll check it out. The sidebar is totally empty and loses the 'Top' lists as well as 'Subscribed' and 'Local' / 'All' / 'Frontpage' also starts returning a blank page?
FYI if this is because of the cross-site attack on Lemmy.world you should know 2FA will NOT help as the attacker accesses the JWT key directly which has already been signed in w/2FA. The only way to mitigate it is to use a native app and not the web or PWA version.
I'll take a look! Comment Navigation is the bar above comments which lets you jump to next / previous comments.
