Why are the domains that are actively used in Web Tracking cannot be provisioned as a Custom LP Domain

Domains actively used for web tracking cannot be used simultaneously for a custom landing page (LP) domain. It is important to decide whether the domain to be provisioned as custom landing domain is more important or continuing the web tracking with the said domain is more important

If the domain to be provisioned as custom landing domain is more important, you must go to the Acoustic Campaign Web Tracking settings and disable the domain in question; if continuing the web tracking with the said domain is more important, then you would need to come up with a different custom domain instead and request it to be provisioned as custom Landing Page domain.
