As of right now, the button is just a toggle that will turn on the feature to hide read posts in your feed, but won’t restore hidden posts (as you found). If you want to see your hidden posts, you can go to your profile (center button on the bottom buttons) and you can unhide a given post from the post itself.

Not sure if this is different depending on the backing browser, but my experience with this is that it works great to open the link, but when you hit the back button to go back to Voyager, you get kicked out to your home page instead of back to the thread you were in.

This might not be caused by opening a page in the same browser as the PWA (could be due to issues with the back button that I think we’re fixed in the latest build? Or was that about the native apps? Can’t remember) but I’ve been assuming that’s part of the issue 🤷‍♂️

If you go to your profile (middle button on the bottom), there’s an option to view hidden posts there. Don’t think there’s an option to filter by community though, which can be tough if you’re looking for a hidden post from a day or two ago.

lemmings, lemurs, lemurians?

I vote Lemurians just for the Golden Sun vibes.
