There is no screenshot I can provide really as I am not sure what exactly the problem is to screenshot.
This is the warning I got from Google Search Console
AMP issues detected on https://www.swankypins.co.uk/
The following warnings were found on your site:
An HTML tag contains the same attribute repeated multiple times.
As Google does not give any clues about the Tag causing the problems, it is very difficult to see what the problem causing the validation error is.
Now I have ‘fixed’ it by removing the plugin and asking Google to rescan the affected pages, on checking this morning there are no more errors. I do want to use the plugin though as my site is slow on mobile but I will probably get this same problem again if I activate it. Have you not heard of this problem before?
Please let me know where is the maintenance mode in the plugin so I can set it up in my own time. Thanks, Debbie
