Hey there! I have run into a weird problem that I think should be addressed.
When an app sends a notification, the icon of the notification is the app icon.
This is a problem for chrome extensions.
If a chrome extension wants to have a unique icon for the notification, it works on windows, but not Zorin. Zorin just uses the default app icon instead.
This should display the same in Linux or in Windows.
I believe that this issue would be better addressed on the Chrome Forum, as this is unlikely to be a Zorin OS issue.
Off-Hand, though - I would also suggest checking on the Linux sub-forum of the Vivaldi (also built off of Chrome) Forum as there are many knowledgeable and helpful members there, too.
