The problem with Fedi apps is that they're built as replacements or clones of other apps like Reddit (Lemmy), Instagram (Pixelfed) or Twitter (Mastodon).
People come to expect the same experience that they had there and they're disappointed by the small community and confused because it's built on a fundamentally different philosophy and concept.
And of coruse, bugs are to be expected. It's not a multi million dollars company that's building these apps but a community of volunteers.
