Rollback, restore, revert...it's no longer in v0 chats. mistake?

Folks, something has gone missing in v0.

I believe it started yesterday. You can no longer restore / revert to a prior version of your chat. Let's say you are at v129, and you want to rollback to v126. There used to be a little arrow button, next to a summary of the diff in red and green (ie how many lines changed). You click the arrow and roll back.

Anyway, it's gone. Hard to believe this is/was on purpose.

You planning to restore? Is there a new way to do this? Please explain. thanks.

hello? Anyone out there?

Same issue here. No idea what's going on. I've seen this before, but it always came back, so I thought they were just in the middle of a glitch. Now there's no way to see a previous version unless you revert. So, say I want to go back to a previous version. When I click on it, it asks me to revert before I can see it in read-only view?
