Hello @tambergirn
Thank you for the support topic, it seems you are using the Jannah theme, it forces AMP settings programmatically which also includes forcing their own AMP template instead of using the AMP plugin’s template.
The Jannah theme forces AMP to it’s templates and disables AMP on Home Page, We will recommend contacting Jannah support.
The code that modifies the AMP settings and forces you to use different themes is located in /themes/jannah/framework/plugins/class-tielabs-amp.php
The template Jannah theme is forcing can be found in /themes/jannah/framework/plugins/amp-templates/ directory
You can use the above code reference to mention when asking for support for the Jannah theme since the issue is with your theme I will mark this as resolved.
Hope this helps!
