Hello. As the title says, my icon packs are not applying for some apps. I think the icon pack does contain an icon for the apps for which the icons are missing example: telegram desktop. I faced the same problem when I was using Zorin 15.3. The apps in which the icons does not change are the apps which I installed form software store or through terminal. But for some reason, icon of one app I installed from terminal called blanket changes icon if I change the icon pack.
Here is a picture for you to understand the problem I am facing
I can see it's from one of my icon themes you're talking about.
If you installed an app from the store that are snap package you need to manually apply the icons. You can do it by the menu editor or by terminal;
