Not the original commenter, but it regularly fails to update emails unless it is restarted. Last 2 major iOS versions have had the same problem for me. That’s a fundamental functionality failure in my book.

This! Continuously restart app to read new mail.

Thanks! I didn't notice it because I only have manual mail fetch. But I did notice frequent crashes of the app when you open heavy email (e.g with lots of images)

It's pretty embarrassing that Apple doesn't bother fixing this issue.
