!Friendica Support

Do someone also use #pixelfed and friendica?
I think, federation in pixelfed seems broken. I know, that likes from pixelfed are not distributed to other services.
But comments are too not properly distributed. I have so many postings with comments on pixelfed, but i almost never get comments in friendica. Sometimes one or two comments are also visible in friendica, but most of them are only in pixelfed.

How does this work with other services like mastodon or pleroma?

Is it a problem from pixelfed or friendica?
I asked several times in pixelfed-chat on matrix... but i never got an answer...
