Okay, so first I thought that I had subscribed to a few communities from different servers and they weren't showing up in my feed. But apparently I never subscribed to them and seem unable to do so.

Here's what's happening: I go to a different instance and browse their communities. When I want to select one and tap "Subscribe" I'm asked to enter my home instance and then am redirected there, it says "Community federated!" but then a completely different community (from the instance I was browsing before) is shown below that with a "subscribe" button. No matter how often I try, I'm never directed to the community that I wanted to subscribe to.

Has anyone else encountered this problem?
