I'm experiencing an erroneous white line that appears in the header and footer element of an email template. The header element comprises of several block built together to give the appearance of a colour block with an offset rule. The white lines appears at the bottom of the block that contains the rule (see below) I've seen that this issue has been reported elsewhere and that specifying the email background to be the same colour as the background of the block where the white line appears to be an acceptable work around. However, in this instance the solution is not viable as it would mean changing the whole email background to be the same colour as the header; blue. Please can an update be provided as to how your engineers are progressing with getting the issue resolved?
