Enable the Jetpack Mobile theme

Hi, I have in "Theme enhancements" the option "Enable the Jetpack Mobile theme" turned on with "Show featured images" & "Use excerpts instead of full posts on front page and archive pages" However this "Enable the Jetpack Mobile theme" seems not to be stable, sometimes it does what it says but many don't. I have tried to adjust other plugins that may interfere with this option but haven't found the solution.

Must have!!

Must have!! useful tracing function, easily and free to use.

Super plugin! Def 5 stars!

This is so wonderful tool! I think such functionality should be installed in core modules of the wordpress in future. Great job!

Makes your site slow

You get a very slow site. This plugin is the first mentioned to avoid from multiple WP experts and speed up guides. It's a heavy plugin and makes sure your site will loose ranking on Google. The performance settings are not as powerful as they think. You get much better options and quality basically from any other plugin. This plugin will work for you who doesn't care about your visitors - Only about having a easy backend. Really sucks you HAVE TO use this plugin to use the Woocommerce app. Would be awesome to get app notifications but I rather choose speed and a customer friendly site over luxury. And at last: Read their Terms & Conditions. You thought Facebook was bad?

Very good

I enjoy this plugin as I can basically have Jetpack give me info on all my sites, I did have an issue but it's since been corrected, other than that it's been great. Thanks for the plugin! Regards, Rudder
