Android Mobile app Message panel

In mobile app no option to turning off side view panel. Mobiles are small screens. I just want to view incoming email list then tap on it if i want to view email. Desktop em clint has options to turn off message panel but em client mobile app does not. Help. Android 14

I’m confused. It doesn’t show the popout left side panel “unless you press the menu top left” ?

Can you you screenshot what you are seeing. Blank out anything personal.

This is the default view on Android mobile with eg: OS 14 on a Samsung S21 mobile phone.
