Comment 0 for bug 1567845

package: gnome-software 3.20.1~git20160331.78d1aab-0ubuntu2

Many applications in Software have reviews written by users. In Ubuntu Software Center users were able to mark reviews as useful (or not) by selecting the correct choice in "Was this review useful to you?" under every review.
Now this is not working anymore.
First of all, no indications are given if people considered a review useful or not (see PNG attached, it's the same comment for Inkscape in USC and Software).
Every time I choose "Yes" or "No" under a review, the question disappears.
Closing and launching again Software, the question is again here but without indications of how many people found it useful.

 = How to reproduce =
 * launch Software
 * select an app with some reviews, then click "Yes" under a review
 * login with SSO
 * then notice that the text "Was this review useful to you?" disappears
 * close and launch again Software
 * select again the same app, then notice the text "Was this review useful to you?" is back

 = Expected result =
If a review has been evaluated from some user, you should read the text "5 of 6 people found this review useful" or similar.
Clicking "Yes" should appear the text "you and 3 more people found this review useful" or similar.
Clicking "No" should appear the text " you found this review not helpful" or similar.
