Adding a review source
Most sources connect by pasting a link to your public profile on that platform.
Three groups. Setup and content covers getting the right reviews into the widget. Display problems covers getting it to show up and look right. Source and platform pages cover the things specific to one place.
Each page starts with the answer and then gives an ordered check, with console error strings written out literally because people paste them into a search box.
Every page in this section, with the rest linked from each one.
Send support a direct link to the page with the widget on it and your widget installation code. Without the link there is nothing to inspect, and that is the most common reason a ticket takes an extra day.
