SUMMARY
Some notifications from the phone are properly creating a 'notify-send' type of notification, the one that appears in the corner of the screen. Some other notifications are instead only showing up in the kcon system tray icon.


STEPS TO REPRODUCE
1. Send a: sms message, whatsapp message, discord message to phone
2. Phone vibrates, notifies etc.
3. At this point kcon sends the information to the desktop
4a. If it was a sms then I get a notification on the desktop as well (same with youtube).
4b. If it was whatsapp/discord I do not get a notification on the desktop. Instead, the kcon tray icon is the only way to see I even received anything.
5. Also, the 'reply' button in the notification for sms (because it shows up) doesn't do anything. Replying only works if clicking the '<-" arrow in the kcon system tray which opens the window where I can type a message. Likewise, youtube notifications seem to have new buttons that also do not seem to do anything.

OBSERVED RESULT
Whatsapp/discord notifications are not properly sent to the desktop, even though in the past they were. SMS and youtube notifications are sent, but they appear to have broken actions.

EXPECTED RESULT
All notifications that appear on the phone should also appear on the desktop. If there is a reply button or any other action button then that should work.
