Hi guys,
I only started using Clickadu, but already disappointed big time. Here is what happened,
No matter what I do, how I tried to change it back, all of my campaigns would automatically have this turned on, please take a look at the screenshot

This is very frustrating, what is more frustrating is that after one week I sent the support a message without hearing anything, I sent a second message two days ago and still haven't heard from them.
Jesus, how are they even in business.
I sent a message to them, hopefully you will get a reply soon 
Hello there,
Sorry for all the inconveniences, but as you can see 'Windows Mobile' is automatically excluded from your advertising campaign. It's not a bug and it was made for purpose as we haven't got much traffic on windows mobile and there are some technical issues related to windows mobile platfrom.
P.S.: Please check your email as our support has answered you via email regarding your application 
Well, that is nice to know. But I would suggest you add a note on the page explaining this as it does look like a bug.
And the support response can surely use some improvement.
Thanks for explaining.
