Domain Mapping user logged in only on primary domain

Hi guys,

I am trying to figure out what is causing the problem, but haven't solved it yet.

Essentially, I am using domain mapping on my multisite. I have run some tests by Directing to original domain and primary domain. I have also tried using exceptions on URLs.

Cross-Domain Login is disabled
Administration and Login mapping are set to domain entered by the user
Force HTTPS are both set off

I am enabling your Support, the site in question is Bassett Biomechanics.

Thanks for the help!
