Unread mark disappearing

[Rinqual]

Hi! When opening an email, the Unread mark is removed only after 1 second. Is it possible to make this happen immediately?

Hello.
Click on Menu - Settings - Mail - Read and on the first line
it says “Mark messages as read after – seconds”
You have to put 0 seconds “Apply” “Save and close”.
