I was able to reproduce both of these bugs on Bionic Daily. 1. I received 2 emails simultaneously but only received one notification on my lock screen. This is expected as Thunderbird only has one notification which states you have 2 emails so the lock screen is right.
2. I read these emails on another device and confirm that although thunderbird marks them correctly as read in the client, the notification remains on the lock screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759158 Title: Improve Thunderbird notifications for Gnome Shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1759158/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
