For example: I tried to search all 3 communities from sopuli.xyz featured in this comment https://kbin.social/m/lemmy@lemmy.ml/t/2938/Which-subreddits-would-you-most-like-to-see-on-Lemmy/comment/6790/
search for y2kaesthetics did not work
for frutigeraero returned only my comment linked above
only for weirdcore succeeded
I have the same problem, trying to add !deutschland@feddit.de ad independent of what I do it doesn’t show up.
