I'm not able to export (bug) but I've been able to check myself what is related to this app:I need web-requests log with time stamp
This rule will break facebook login for apps and therefore can't be added for all apps.
I tried to log off and login with FB for this app and it works so at least add this rule by default for this app!No. You can use this rule to block FB ads in the apps. If FB is used for ads only, we can add the rules to the filter.
