I never use Discover, unless it's to install something KDE specific and I never use it to update. If you are using openSUSE Tumbleweed and want to get rid of Discover Notifier, run this:
sudo zypper rm --clean-deps discover6-notifier
sudo zypper al discover6-notifier
These will uninstall the notifier and lock the package so it isn't installed in the future, which it typically is by default.

KDE Plasma 6.1 was released on 18 June 2024 and it has been updated in openSUSE Tumbleweed with snapshot 20240622. It seems to be running very smoothly for me. This release comes with several new features and improved Wayland support with the addition of Explicit Sync. Read more on KDE Plasma 6.1's official release announcement.
Also, there is the Reef wallpaper made for 6.1, but not included with the release, you can get it here.
