As a reminder of standard review practice, advertising/promotion systems (APS) such as websites, which have established breakpoints for consumption on various devices (e.g. mobile vs. desktop vs. tablet) should be submitted as separate files for review. The reconfiguration of the layout to address the specification of each of these devices, generally results in a change to the flow and presentation of content such as menu presentation, functionality, copy/visual flow of content etc..
When using QR codes to link to websites, please ensure that the efile number for the mobile version of the format is submitted. The design and nature of a QR code is that it is intended to be scanned with a mobile or tablet device.
