After updating to iOS 18, the mail app filters (flagged emails and unread emails filters) no longer work properly. If you choose to activate any -or both- of those filters, your aggregate inbox (where you see all the inboxes of all your email accounts combined into one inbox) shows up as empty (see attached screenshot) regardless of having unread and/or flagged emails, those will no longer show up at all. In my case there are 100s of flagged emails in all my
inboxes and several unread as well, but none of those appear as soon as you activate the email filters. So the only way to see unread and/or flagged emails after updating to iOS 18 is to have the flagged and unread email filters de activated.
