I have an iPhone XR running newly released iOS 13 GM Seed. After upgrading to GM seed, I noticed all but my exchange account had completely empty mailboxes (the servers had plenty of mail, just not the Mail App) I read some troubleshooting that recommended deleting mail accounts and deleted mail app and reseting all network settings and then rebooting my device and downloading the mail app and adding my email accounts one by one, but still when I add an email account I am left with empty inboxes (just says "No Mail").
I rely on my email for work Can anyone help!?
Also please note, I have one Gmail, one IMAP account and one Exchange account.
I am having the same issue. XS Max.
