No, @Felix Felix, there is no real app. What you have it’s a PWA application.
Here I explain it Notifications, along with the types of notifications -and difficulties- that actually exist on various devices/platforms.
I am in the position as @solvann, as I usually have a forum tab constantly open in Chrome on my PC while working, or else I check the site periodically. For mobile users it’s more complicated (even for Android ones)
Feedback like yours and @emp is important to know what our usage preferences are, to adapt to what is available now, but also to see what new options are appearing or can be developed.
