I have an iPhone 16. I am unable to use landscape mode with my iMessages app. This is the only app in which landscape does not work. I’ve turned on and off the orientation lock. I’ve closed the app and restarted the phone. It still does not work. Suggestions?

Flip your phone, so it goes into landscape mode.
