Memmy - An iOS client for Lemmy

I just can't figure out how to navigate to this. I have a dozen subscribed communities in Lemmy World. I downloaded the Memmy app for IOS and I'm logged in using the same user id/password. But I don't see my Subscribed communities content anywhere in the app. All I see under Feed is a stream of every random topic/meme...which I have no interest in whatsoever. I just want to see my subscribed community content. What am I missing? I've tapped on all the buttons and can't get to my subscribed communities.

Help?
