App Inbox | Change Font Size?

I am using the latest (as of this date) app for ios. I am finding that the inbox view is unaffected by font settings. I found font settings in the app only for reading, I would like to see an overall font setting for the app as it defaults to a rather clunky to me sized font. The app is also not picking up the global font size that I set in IOS. In the apps current state I can “see” in the inbox, four maybe five depending on day and that is with only one preview line being displayed. Contrast this with the outlook app and I can see several more emails with 3 lines of preview in a single screen.

What are my options here to make emclient mobile app for ios inbox more legible?
