The issue:

..mobile browsers will wait approximately 300ms from the time that you tap the button to fire the click event. The reason for this is that the browser is waiting to see if you are actually performing a double tap.

(from a new defunct https://developers.google.com/mobile/articles/fast_buttons article)

touch-action CSS property can be used to disable this behaviour.

touch-action: manipulation The user agent may consider touches that begin on the element only for the purposes of scrolling and continuous zooming. Any additional behaviors supported by auto are out of scope for this specification.

Declared ETags, together with Russian Doll caching, can be used to automatically mix your template and asset versions into the ETags set in your controllers. This avoids the need to blow all browser caches on each deploy and neatly contains the scope of "freshness fallout" when you tweak a view.

To include the template's version in the ETag:

  # Incorporate the cache version for this action into our ETag.
  # This allows template changes to bubble up into HTTP cache
  # freshness and bust browser caches when we make changes.
  etag do
    begin
