Focus "Silence notification from selected apps" not working properly

Hey,

I am trying to set up a Weekend focus on my iPhone 13 Pro with the setting of "Silence notifications from" only the 4 work-related apps I have on my iPhone. However, when set and activated the focus silences notifications from other apps as well (ie. Whatsapp, Instagram, etc.).

I found no solution to this issue, even after updating to iOS 16.6. Do you have the same happening to you? Any fix?

Ps: only way to avoid this is to set the focus on "Allow notification from" and select all other apps - which is suboptimal and need to be updated whenever I download new apps. I am asking you for any other better solutions

Many thanks

Marco
