Hi there, thanks for the link, it solved the mobile menu issue in Standard AMP template mode.
The AMP flash is green, and the ‘Powered by AMP ⚡ HTML – Version 2005151844001 https://domain/’ is displaying in the console, confirming that it is a valid AMP page.
But there are no /amp in the url, which I have read there should be, how do I check that the pages are actually served as AMP?
Apparently the pages are not AMP, as I see my normal GP design as before, and not a more simplified design as expected, and there are no validated urls in the AMP dashboard.
