Hi Duece2x2000 -


We are aware of an issue that is affecting the Xfinity Home Mobile App & Subscriber Portal.  Our engineers have been and continue to actively work on this issue. When resolved, App & Portal functionality will be restored & nothing will be needed to be done on your end.  I will provide updates to the pinned message at the top of this thread as they become available.  I apologize for the inconvenience and thank you for your patience.
