Hiding was also my favorite feature from Apollo. I’d just go through the feed swiping to hide posts, because if I didn’t then when I refreshed I’d be scrolling through the same posts over and over again.
I will take onto this and ask is there a way to search for communities? I thought I saw one after I logged in but now I can only seem to find the all post/subscriptions page.
I’m not sure if this helps, but if I’m looking for a specific community I go to the search tan on the bottom, start typing what I want to find and tap on ‘community’ and it shows relevant ones.
