Xfinity Stream Version 5.2 Build 0 Probelm

Hello - one of my ROKU TVs has the xinfity stream app version 5.2 build 0 installed (it is on a Sharp 43" TV that had Roku installed on it.  I do not have  ROKU branded streaming device plugged in).  It looks like this got installed back around 6/25/20.  I have noticed that after watching a channel for a few minutes, it tends to drop the connection and then it comes back a few seconds later.  This happens over and over again.  My other devices have version 5.1 build 1 installed and do not have this problem.  I am not sure if this is a known issue with this version or if it is being addressed - or if there is a fix.  If it is not a known issue, I would like Comcast to be aware of it - consider this a bug report.  If this is a known issue, can someone let me know of a workaround or a fix?

Thanks!
