First, I don't expect any sympathy on this from you all. I'm just posting with a slight hope that someone from Apple might see this, and because I want to vent. 
Our corporate email is on an Exchange server and our MDM is configured only for the native Mail app. Since iOS 13.0, everything conceivable has gone wrong. Banners, sounds, delays in downloading message bodies, emails not deleting, and most recently emails not showing up in the Mail app at all, even with a refresh or a restart. I've tried everything imaginable, including repeatedly deleting and reinstalling the profile, deleting the Mail app, reinstalling iOS, setting up as new, you name it.
I guess writing code for new products like the Beats headphones and selling services like TV+, Music and News are all more important than a core app like Mail.
I. Give. F******. Up. Hey, Apple, if you're reading this, I'm putting my 11 Pro Max back in the box and maybe on Swappa. I just bought a XS Pro, just like the one I had until the 11 Pro launched. It's got 12.4.1 installed and it will work, unlike the bug-ridden train wreck that you're calling iOS 13. Great job,
- and thanks. It's been real, and it's been nice, but it ain't been real nice.
