Hey, Thanks for reaching out to us.

You can prevent the blocked package error from appearing on the screen of an Android device in Kiosk mode.
To block the error message:

1. Navigate to Policies and click on the kiosk policy.
2. Go to Kiosk Lockdown-> Android Kiosk Lockdown-> Peripheral Settings-> App Settings and disable the option ‘Show blocked package name on the device’.
3. Associate targets and save the policy.

The blocked package errors will now stop appearing on the device. However, please note that this will not make the blocked packages accessible.

Cheers!
