This is something that I couldn't find an obvious setting for, but someone pointed out that the descriptions are different on different instances.

This post has a German (?) description on midwest.social, but on programming.dev it's in English.

In my settings:

  • Interface language is Browser Default.
  • Languages has Undetermined and English selected

All other descriptions on posts are in English, only youtube seems to be different.

    I recall that some Mastodon instances were all showing YT links in German. It was a YT problem at one point because even Threads was having similar issues. Not sure if that was 100% fixed yet.

    Of course @Ephera@lemmy.ml's comment makes a lot of sense, too.
