Multiple problems with WP Reader: can’t access comments, stats, etc

I recently migrated my site to a new host, redirected the dns and launched it live.

In general, I cannot access anything to manage my WP site through the WordPress Reader.

My recently published Post listed in the WordPress Reader is not showing an add a comment space, rectangular comment sign, star likes sign but it does have the ‘share & reblog’ symbols. Also, there are no Subscribers listed. There is no way of managing comments, etc in the Reader.

Any comments/likes received are visible only by logging into my website dashboard directly and not visible in anyway via the WP Reader.

Also: The “Sites” sidebar lists my one website as two (the same) active sites.

Other problems include inability to access Jetpack stats in the WP Reader such as: “View your Site’s Traffic”, “Views & Visitors” etc ?
I have re-checked all my Settings directly on my website Admin with Jetpack as follows:
My basic Jetpack Settings configurations –
Sharing buttons in Sharing section is enabled. Let visitors use a WordPress.com or Facebook account to comment & Enable comment Likes in Discussion section are enabled.
In addition, comments, comment likes, likes are all activated on my Jetpack module page.

Because these issues seem interrelated, I have a help request in the Jetpack WP.org Forum pending about the Jetpack portion of this problem also.

Thank you in advance for your attention to these multiple issues.
