GA - Different domains / cross domain tracking

Hey everyone! 


I'm having trouble getting cross domain tracking working correctly. Using GTM. The trouble I'm having is, while I can track the sessions on both domains, the source / medium is being dropped when the user goes to the secure store to process their order.  Here are my settings. Not sure what the next step in solving this would be so any help or direction would be greatly appreciated! 


Would going from http to https be an issue?

Under the Auto Link Domains.. entering both and isnt necessary.
just will cover any possible subdomains for that domain too eg / etc
Same applies to . it will cover and

The other thing to look into too.. are both domains and both added to the
Referral Exclusion List? The do both need to be added for cross domain tracking.
