The domain name for the Potomac Arts Academy changed to from potomacacademy.gmu.edu to masonacademy.gmu.edu on January 4th.
As a result of the domain name change, there was a gap in analytics data collection from Jan. 4 through Jan. 8, when the GTM settings were updated with the new domain name. GA settings were also updated to reflect the new domain name.
I have upgraded the GTM container to version 3.2 of the Mason standard GTM container functionality.
