Maybe this is Theme related, but in my Mint Theme the default buttons which are here on this site and in the Xi, are not evident on my most recent Mint install. I have had to enable the Jetpack Share option in order to make sure such buttons are present for mobile environs. Does this observations make sense? Is this theme related?
Thanks – I have actually enabled the Share option. I am using Shareaholics and like the movement it adds to the page. The WP share keeps it clean in the mobile environment yet retains that functionality. And it is helpful to know you have made a choice with this Theme and it makes sense too fwiiw!
