I have fixed this bug or feature.
Google tries to find this line of code on your page
<g:ratingbadge merchant_id=__MerchantCenterID__></g:ratingbadge>
Plugin didn't add this line of code for INLINE mode.
Now plugin adds it, but you can change it if you need.
Download the new release and try.
Version 1.01 - March 24, 2018
- fixed bug "wrong place of badge for INLINE mode"
