AllAccess MacOS (Mojave)

Att AllAccess causes Mac OS to throw the "Error/Reminder" box indicating I should contact the vendor to update a 64 bit version of the application.

I am running Mac OS 10.14.2 on a MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports) so I have to use a Thunderbolt to USB converter pigtail.

So the question is: Has anyone else seen this and does Att AllAccess know when the 64 bit version will be released?
