Oh, Adblock mobile(64 bit) hasnt been supported in months. On 11.3? It might work, but with dns leaks-yes, its an actual DNS that uses a dummy VPN to work.
That's all well and good. Still, it is very insecure. With the adblock I use, I am also able to use DNScrypt. My point is: You want adblocking...do it right or it's just a Band-Aid. Sorry, i'm an engineer and a developer. I'm here to give real world advice, not read 30 posts on how the new beta is out and how my battery life sucks after just installing the most recent release. I would really consider ditching Adblock Mobile based on the facts that !. The servers won't be around much longer, 2. Severe DNS leaks, and 3. Eventually, ios will break the functionality.
