When activated with the new sharing features any article excerpt on the homepage, when click on will display the entire article text content above the site's header. The regular post is also shown normally below within the post space. I had to disable the jetpack plugin completely.
This code is in the header of a sample page that is affected:
<div id="access" role="navigation">
<div class="skip-link screen-reader-text">Skip to content</div>
Let me know if there is a bug fix for this or what. I'd like to roll back to the old Jetpack until then.
