It's a different issue.
I too have issues with posts and comments not showing. But there can be two reasons :
- As explained in another comment, languages settings. On the web interface, in the settings, you can select which languages you want to see. Select all of them.
- Synchronization issues between lemmy instances. Sometimes, packets are lost between instances, for example when the versions are different.
My current issue is only on the Arctic app. I can see the content on Mlem and on the web interface.
"Default post filtering" ?
It's "Subscribed".
Edit. Sorry, "Default comment filtering" is at "All". But it's posts that I can't see.
