/amp pages giving 404

Hey guys – we’ve installed the AMP WP plugin, but all /amp pages are giving 404

e.g. https://getblys.com.au/amp/

Concerned that this is having a negative impact on our search results ranking as the site now has a bunch of broken links.

This is the response we received from wordpress.com support:

“You might need to reset your site’s Permalinks by going to Settings → Permalinks in your admin (you don’t need to do anything on that page; just visiting it is enough to reset them).

If that doesn’t work, you’ll want to post a request for help in the plugin’s support forum.”

Any help would be much appreciated.

Cheers!
