I met several problems with the version 2.25.
On the beta WME the add-on doesn't appear at all. Details of the extension show that it has permissions to read and change data on editor-beta.waze.com and
www.waze.com. But the URL of WME beta is beta.waze.com!
On the regular WME, when I select a city in the "Filter by city" combo box, the check box is indeed selected by itself, but only segments belonging to the chosen city are marked yellow. Places aren't marked. I have to unselect and select again the check box to see also the places marked yellow. Then, if I select another city in the combo box, new segments become yellow, but the places belonging the first place still remain yellow.
