Strikingly needs to support Google Accelerated Mobile pages. Wordpress, Squarespace, Reddit, Medium, Linkedin, Twitter, and Pinterest all support and use AMP pages already.
Strikingly doesn't. If Strikingly doesn't support AMP pages soon, our users will have comparably worse experiences, and our sites will perform poorer in the SEO rankings due to lower click through rates and share rates (speed is an important ranking criteria).
