Getting errors, need bugs fixed that were not in previous app

When its working its OK, but it takes forever to start up once I click on the app. It shouldnt take that long to connect to its server and get the information I need to browse TV channels. The previous app I had from Comcast didnt do that at all. In fact it worked seamlessly and I rarely if ever got any errors. I get the "need to be in home" error as well when I am in fact in my house. I am tempted to and have in the past deleted this app until they fix it.

Unhappy with comcast app about Xfinity Stream, v4.3.1
