Comcast on iPhone?

I just put the Comcast business app on my iPhone. It shows what channels I am receiving. However, I cannot watch them thru this app. I also have the Xfinity TV app. I can watch tv at home, with my home account, and at my work thru my business account. However, when I switch from home to business all the programs that I downloaded to the phone are returned. Is there any way to get around this? I would like an app for home, and one for work. Anyone have a suggestion?
