I typically use Times New Roman 12 font to compose emails. However, on my Mail app this appears very small and a strain on the eyes after a while. I cannot find a way to "zoom" e.g. by the 2-finger spread technique that seems to work on just about everything else. I am having to draft in larger font to see comfortably, then reduce the font to send. Am I missing something obvious? The "problem" is only on the composition screen. Once the message has gone, and similarly with received messages, I can increase the viewing size -- simply not when I'm composing/drafting. Grateful for advice.
