You have to open the APB app and manually configure it in your network settings if you haven't already. The option to do that is at the top of my screen on my phone. This is the part where you have to use "localhost" for the proxy and enter the number "2020. If that doesn't ring any bells, then you probably haven't done it. LOL

You will probably also want to uncheck the "acceptable ads" option. There's also a refresh icon on that page when you open the app that you may want to use after you make changes there.

That being said, I did all that. It seems to block the ads on your Chromebook group, but I am getting a Quizcode ad on another Boardhost group. I really didn't surf around all that much on my phone before I installed the app, so it's hard for me to tell how well it is working. I'll keep it awhile and see how it goes.
