I have created my emails in HTML. I am trying to do an A/B test for the entire email body being different, but every time I choose "B" in my A/B test to edit that email alone, it edits both email bodies identically without me making any changes to A.
Error Code: MessageContentValidator_PartCode_Mixed (A/B Test 'Full content test 1'): Your message body is identical for each variant of your A/B test.
How can I just edit the HTML on the one email body?
