I've got two Android devices; both with German data plans.
One is on BASE (5GB high speed data)
the other is on O2 (.75GB high speed data).
Both used to have Adblock Plus installed, then...
...on the first device I received a warning that 90% of my monthly data volume had been used, when I was sure that I could only have used less than 3GB.
The list showing data use displayed, at the very top, "Adblock Plus 2.7GB". - I uninstalled Adblock Plus.
A few months later the second device gave the same 90% warning, when I only had received a large number of text messages (mostly for two factor verification) and updated a few apps; here a closer look showed "Adblock Plus 640MB". - Again I uninstalled Adblock Plus.
Can anyone explain this nasty behaviour to me, and is there anything I can do to avoid a repetition? I'd REALLY like to reinstall the app.
