Thanks.Check the settings fo Accessibility. There should be both default text size (which I presume the Mail app respects), and/or you can enable the Zoom feature...
Thank you for your input, and text size adjustability does increase the text for many things.Accessibility should show a Text Size option. On a S9. I don't know if that changes by watch. I've only had a 7 and a 9 and they both had the option in Accessibility.
Thanks.If you double tap on the open email it expands to a big size that you actually have to scroll through left to right, etc. just to read a line. It goes to the other extreme, but it helps me occasionally.
