Hi Lynden_Waldner, additional firewall tweaks were made and recorded as per the new video link in the following article: pfSense firewall rules for WhatsApp on Android
This has worked for 100% of our managed Clients thus far.
As far as the traffic log not showing any blocked traffic, it could be an indication that a rule within pfSense itself is blocking traffic since they are upstream from the adam:ONE service itself. Just a thought.
