All Inboxes does not refresh even after new mail is fetched
All my All Inboxes fails to refresh even after the mail itself is pushed or fetched. If I back out of All Inboxes and then go back in, the mail is there. Happens on both iOS and iPadOS, even after a fresh reinstall. I am using a iCloud-Account and two O365-Accounts.
This Problems starts with iOS13, i think. I can reproduce is even with the latest iOS16 on a freshly installed (without backup) iPhone 14 Pro.
