Hello everybody! I have a problem with the Judge.me app, when I or anyone else tries to click on 'write a review', nothing happens. I have contacted with their support and they have told me that it seems to be a problem related to facebook (?) and they have send me the following video:

Could anyone explain to me what this means and how to fix it? Many thanks in advance!

Hello @medcanuni,
You need to talk with judgeme app support for this issue.

I did. They sent me this video and directed me here.

I have the same issue.  I tried it from different browsers and still could not get it to work.  I have one customer who has been able to submit a review but others who they click the link and it just takes them to the product without any way to do a review.  I tried to click your video link, but it errored.  And the facebook excuse doesn't work for this case because these were direct sales on my site and emails sent to them from the judge.me app.
