 * Is there a way to cache v0.js, or even better, use a local v0.js file instead?
 * I’m using the Avada theme for non-AMP pages, which has good performance settings,
   and I’d rather not add a caching plugin to the mix.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcaching-https-cdn-ampproject-org-v0-js%2F%3Foutput_format%3Dmd&locale=en_US)

 * I think I’ll leave it alone. On further research people are saying it’s fine 
   because users probably have it cached and it invalidates the AMP page if the 
   file isn’t loaded from their site.
