URL Blocking not working iwth mobile devices

[Bill]

This might be a known issue but I couldn't find it in the faq. When I block a third party script (in this case just to test, I picked Jquery) on mobile devices its not actually blocking it.

So here, I block jquery but if you check the connection log it's still running and downloading the exact script I blocked.

Should work fine with Chrome and Samsung browser on Android devices but iOS doesn't support request blocking (or header manipulation).
