Some federated posts are not displayed for the following actor

We have set up a tag actor on one Discourse and a category actor on a second Discourse, who follows the tag actor on the first.

Unfortunately, not all posts of Hello bibcourse.eu - Meta - metadaten.community are displayed at Hello bibcourse.eu - Website-Feedback - Bibcourse
If i see it correctly the posts with images/attachments are affected.

According to the JSON logs for the following actor the missing posts have been delivered and received but just not displayed.

Do you have any ideas what is going on here?

Btw, some other (minor) errors are discussed in the topic like

  • Emojis within the posts are missing on the receiving part
  • Emojis as reaction are swapped eg. :heart: on side become :thinking: on the other side
