Beginning with iPadOS 14, when I read my email using the native mail app on my iPad Pro (12.9-inch, 2nd generation) in portrait orientation, the unread mail count in the upper left hand corner of the screen does not change after I’ve read an unread email. (In contrast, in each email the blue dot next to the header disappears.) The count only changes when I exit back to the list of emails in the inbox. Updating to iPadOS 14.2 did not fix this. Neither did a force restart.
Has anyone else seen this bug after updating to OS 14?
