Been searching and figured I'd ask here as a final ditch effort. The Mail app on my iPhone 7 plus on ios10 has tiny tiny fonts for HTML emails. So far I've tried: Adjusting font size in accessibility. Restarting phone. Closing app in background and restarting. And every combination of the above three therein. Does anyone know of any solution besides the ones I've tried, or is it simply a bug that needs to be fixed? I hope its soon if so, because it's ridiculously annoying and I'm floored, absolutely FLOORED, this issue didn't come up in the beta.
