Issues with mobile responsive branding file

Summary

Branding partner unable to get formatting correct on file

Content

Hello

We have been trying to move to the mobile responsive branding file for the last 6 months and we have been going back and forth with our branding partner to try and get the formatting working correctly.

What we have done so far:

• Taken the mobile responsive branding file template which was posted on customer connect around 2 years ago
• Sent to branding partner to add Co-op branding
• Added this to both external and mobile career sections (both are linked)

The branding looks fine on the external however the mobile the formatting is all squashed (see images). Is this a problem with the file or with the settings? I can't seem to find help anywhere and this has been ongoing for months and months so any help would be appreciated.
