Are you on mobile or are you using desktop? The mobile app is definitely still in development so it’s missing a lot of those QOL things that you are missing.
For me it’s been helpful to use that fediverse search tool, and copy and paste it into the search. Seems to work better on desktop. I’ve got a decent feed going today, but it’s definitely a work in progress.
Holy crap, that’s fast. Kudos!!
