If mobile.pipe.aria.microsoft.com is blocked the App flood the network with constant DNS Requests.
I'm using one DNS Blocker and I noticed that when mobile.pipe.aria.microsoft.com is blocked the Android App (even while not open on the mobile) goes into a infinite loop of new DNS requests searching for mobile.pipe.aria.microsoft.com address every 10 secs.
I had to uninstall the app to fix this problem.
