On my nexus 7 rooted, I installl adblock to block ads directly within the os. I use the esaylist and recently I experienced a problem with the kijiji app. When starting the app and selecting a city/country, Ican see the ads at the left but if I select one, nothing appear at the right. If a disable adblock , everything works coorectly. We can add a whitelist for this version of android so I stuck to enable and disable everytime.
Thanks for help.
