@casino You need to check the logs in Raw view to see the blocked domain names and the block reasons.
Black/white lists and calendar entries are separate from each other. White listing a domain does not make it available for all times. You need to create another calendar with broader time slots for the more specific domains. I.e., you need to create a new calendar for mobile-webview.gmail.com, inbox.google.com, etc., and assign to it the time slots you want those domains available.
