I had left a review on the App Store warning users that Memmy is still broken for any instance that uses late v18 or any v19. The dev responded that they would issue a fix soon.

Still, since I needed something that works, I tried a few of the many Lemmy apps. Voyager is nice, but Avelon is the only app that stays in portrait while I scroll lying down, so that’s what I’m using presently.
