Solution: Check your language settings in the web interface.
I have a weird bug when I visit !ich_iel@feddit.de from jerboa:
Though when I visit anonymously through the web client the com is active: https://feddit.nl/c/Ich_iel@feddit.de?dataType=Post&page=1&sort=New
Until I log in, that empties all the content to the same level as in the app.
What is even going on? I blocked like 5 communist missionary users, but not 95% of a community.
