I revisited Neptune after a period away and was very impressed with the latest version except for Thunderbird. As someone who relies on notifications for new emails for home business I’ve no idea why Birdtray is still in so many repos since it hasn’t worked for some time. The usual workaround is to use the flatpak versions of Thunderbird and Birdtray instead which do work except for it would appear Neptune. Sometimes this needs a combination of using X11 instead of Wayland and/or some Flatseal permission settings but I’ve tried everything I know without success. With Neptune and flatpak Thunderbird the initial new email number is recorded correctly on the tray icon but it then it stays frozen no matter what you mark as read or add in the way of new emails. Does anyone have any suggestions?
