@moshiphoto thanks for reaching out!
When I view the details of the theme, I’m not seeing stated AMP compatibility. This means that theme may be adding restricted code/ markup on AMP pages (see the AMP specification).
The plugin automatically removes this markup in order for the pages to pass AMP validation, which may lead to some visual changes like the one you are describing. It looks like you are using Standard Mode which serves the site as fully AMP. I recommend switching to Reader Mode (and one of the Reader mode themes), which serves a different theme for your AMP pages alongside your non-AMP pages. You’ll then still get the speed and benefits of AMP in this mode.
If you’re aiming to serve your site as fully AMP, you can inquire with the theme author if AMP compatibility is on the roadmap. You can also explore AMP-ready themes and plugins on our Ecosystem page.
Thank you very much for your reply! I will try in reader mode and also contact my theme authors to check amp compatibility to make the site fully amp. For sure I have to figure out how to keep using your plugin in my site, you took me to 96 into the pagespeed insights!
