Upvotes and Comment replies don’t seem as accessible.

I’ve noticed on the homepage, despite the upvote button being there, it doesn’t seem to work unless I go to the page for the item or submission. I also find the comments to be acting a little weird, with not automatically being able to reply to commenters and the number of replies being limited. I also find it odd being unable to reply to reviews anymore.

Totally hear you - that’ll get resolved soon-ish. We’re in the middle of shifting the site to a newer, faster, cleaner layout (the forum, for example, is still on the old one). We’re not doing much maintenance on the older layout anymore, since the focus is on improving the new version, but some pages - like your personal homepage feed - haven’t been fully converted yet.

It shouldn’t take too long to get to it. As we move these pages over, it’s been great to take a fresh look and finally squash a bunch of long-standing bugs and little annoyances you all have pointed out over the years. Appreciate the patience... lots of improvements coming soon!
