We have 4-5 company-owned domains using the same Marketo account. It was just brought to my attention today that if a visitor has js disabled (very uncommon) or has a privacy add on to their browser (much more common), then the Marketo scripts are being blocked. This means no forms and no tracking.
I came across an article that mentioned changing the <script src="//app-sj01.marketo.com/js/forms2/js/forms2.min.js"></script> script and replacing "app-sj01.marketo.com" with our CNAME. I'm not sure how I would do this on multiple domains, however.
Which domain's DNS settings would we add the CNAME to?
Do we need to do it on each domain?
Does it matter?
I was chatting with support about this, but apparently the question was too hard because they just pointed me here and left the conversation. They came back, but said nothing and left again...
