Hi there,
I can get this problem solved for you in great time. I'm an expert programmer and very capable with AMP and CSS. I would start on your project and not stop until it is finished, so that it is solved for you within great time.
Please see my profile to check out some reviews, I treat every project as if it was my own work, so you can be assured of 100% attention to detail, and a great all around project experience.
I will also fully backup any pages/data we are changing, to ensure you data is 100% safe.
if you would like I can make you a video to show you how I solved the issue.
Best,
Gary
