I am having the same issue - mail not downloading even when there’s the notification icon on the app badge. And after I open the email and go back to my inbox, it’s still unread. Or if I delete it, I have to delete it twice because it acts like it’s working and then the same email opens.
I am also having issues with my Touch ID for passwords - seems to not really work on some sites. I have to click on the login area before the Touch ID box appears.
Its been a week since this update came
out. Please fix these issues. They’d both concerning Apple apps/functions. The mail app not working is pretty unacceptable.
I have iOS 13.1.2 on an iPhone 8. Issues happen on both WiFi (multiple networks) and Verizon’s LTE.
