Your software
My Mautic version is: v3.1.2
My PHP version is: 7.3.25
Your problem
My problem is: email with dynamic content block that has 1 variant gets sent and all recipients get default content only even though some should get the variant content. Rule for the variant is ‘Marketing Details’ contains ‘eCommerce’
These errors are showing in the log: none
Steps I have tried to fix the problem: remove filter on variant, add it back, apply, close and save.
