Minor Issue popped up

I have been very satisfied with this app for some time now. It does everything I want it to do.

But about a week ago, the key pad to select station numbers directly went gray and stopped working.

I hope this function can be restored.

Problem fixed today 07/26/17
I also had a problem watching many channels.
It told me I wasnt on my home network when I was.
Looking at Devices in My Account I saw it was showing my old modem which I replaced.
When I talked to a Technician she added my new modem to my account and streaming tv is working properly again.
Everything was working ok with my new modem when I activated it.
I think Comcast reverted to an old Database that Streaming uses to check validity, but Im just guessing what went wrong

EugeneU about Xfinity Stream, v4.3.1
