iOS 13.1.2 - Email not being marked as read when I read it

Hi, had this problem with every version of iOS 13 to the [current] 13.1.2.

When I select an unread email, it goes into the email and doesn't mark it as read.

Also, if I press the delete button on an email the email 'swooshes' off the screen and the same email is presented to me underneath, without it being deleted.

Just putting it on here so Apple have more awareness of the problem (yes, Apple staff do 'watch' the discussions).
