OK. Google changed something again and now ads are showing again so an Update needs to be done for this Add-on please.
UPDATE: Thank You Alexandre for your extremely prompt response and Add-on maintenance update work. v2.7 was definitely the fix.
Please keep up the great work.

This review is for a previous version of the add-on (2.6.2). 

Extension updated

Feel free to update manually to version 2.7 on this page (See this addon's description for more information):
