Is there a technical problem on this instance that hides many other communities?
For example if I search all communities for 'games' on this instance it only finds [email protected], but if I do the same search on another instance it finds about 80-100 communities.
I took a look at feddit.ch/instances to see if there are any instances that you block but this is not the case.
Could it be that your instance is somehow configured to only show german speaking languages (that's maybe why it only shows one german community)? I saw another post here about a user unable to comment on certain posts without choosing a language.
Thanks for explaining, I didn't know that. I thought an instance sees all communities from other federated instances automatically.
