SUMMARY Always when a mail arrives into my Gmail account it appears in three folders: Inbox, Gmail/Important and Gmail/'All messages'. Reading the mail from one of the folders doesn't mark it as 'read' in the other two. I would expect all three messages (it's the same message) would be marked as read. Thunderbird does this correctly. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.16.0 KDE Frameworks Version: 5.59 Qt Version: 5.12.4
Issue is not present in the current version.
