Thanks!
The mobile is running on android 13 and One UI 5.1.
KSK version is 1.103.0.3
Samsung Knox permissions have been applied (approved during install)
Regarding the Application Monitoring settings, Age restrictions based on public age-appropriate ratings is turned on.
On the application list most applications are allowed (the default setting) with a few exceptions "available on blocked device" like school related apps and apps like Contacts, Messages, Camera, Settings etc. Additionally there are 2 apps with custom settings: Snapchat - restricted for 1 hour and Galaxy Store - forbidden.
About root / admin access, the phone has never been rooted and is still in "default factory" mode, running default android supplied by Samsung.
Also, the default Google Play Store is used for all apps installs like KSK, no other stores.
Today I've enabled the alerts again.
