Can’t wait for the Boost app!! It was such a great Reddit app, so I’m eagerly awaiting the Lemmy version.

If you click on the name of the community (in one of their posts in “All”) it’ll take you into that community, and you can then click on the “vertical 3 dots menu” in the upper right corner, where you’ll have the option to block that community. You can then just swipe left to go back to “All” from there

I’m trying Liftoff rn for the very first time and this method seems to work (for me at least).

HTH :)
