Just tried to hide a post (don't like pictures of spiders) and it didn't disappear. It just sits there (like a gross spider) and the only difference is if I click on the menu it now has Unhide as an option. Which also doesn't visibly change anything.

I've tried it a few times, closed and restarted the app. Doesn't seem to make any difference. I've used hide before (but not for a while) and it worked fine, not sure what's changed? Or is it just a glitch?

Edit: solved! Show Hidden Posts had been turned on, so it was working just as intended.
