Comments and posts not shown on Lemmy servers

Hey. I have issues when I comment posts, then sometimes it doesnt show up on the Lemmy server where the post was originally posted.

Another issue is that if I try to make a post which contains a picture, then it doesnt work - only if it contains text only. What I do is that I tag the community, I want to post in.

This is my Friendica account, but I have the same issues from my Mastodon account as well.

Has anyone else had the same issues when interacting with Lemmy instances from other Fediverse platforms?
