Widget no longer appears as entry in System Tray

[moconnor1234]

I am currently running OpenSUSE Tumbleweed, which recently updated KDE Plasma to 5.11.95 (aka 5.12 LTS beta). Since I rebooted after the install at night, I immediately noticed Redshift was not working. I can still use the widget if I place it as a separate widget in the taskbar, but it will not appear as one of the icons in the system tray and is no longer listed on the available entries to enable.

Is there some way I can fix this? How would I diagnose the issue? Is it possible it will be fixed when the stable release of KDE Plasma 5.12 comes out?

Ok, found a fix. this command will fix the issue:

kpackagetool5 --generate-index -t Plasma/Applet

It also works with other widgets that may not appear in system tray. Here's the bug report I found that explains the fix: https://bugs.kde.org/show_bug.cgi?id=386880
