Everything imported fine, but it has not updated since I installed it. Going to use Feedly instead.
This review is for a previous version of the add-on (1.8.1.1-signed).Once you have imported your feeds you need to click on the "update" button (or activate automatic updates).
I think it is not so complicated.
Saying "does not work" is simply a lie.
