Memmy - An iOS client for Lemmy

Let’s say I’m not very tech-savvy so no idea how to ask for help or what is going on. Since the app got a new look I can’t reply to any posts in the communities I’m subscribed to. A pop up in red appears on the screen and my reply is not submitted. I know this probably sounds unbelievable lame but the pop up shows so high up on the screen that it’s impossible to read the text! What is going on?
