I use Adblock Plus V1.3 for Android and have Android V4.1.1
When Adblock Plus is active, the "Die Zeit Digital" E-paper app (German weekly newspaper) can't access the server and shows a message, that the connection to the server is not possible.
Please note that the E-paper app is NOT the same as the webpage "www.zeit.de".
As soon as I deactivate Adblock Plus, the problem is gone.
