Streaming pauses on Roku

I have been using the Roku Xfinity Stream app for over a year w/o issue.  As of a couple of weeks ago, every 5-10 minutes the picture freezes and the three dots appear while it tries to begin streaming again, which it always does.  Problem does not occur on other streaming services on the Roku (Disney+, Hulu, etc.), just the Roku Xfinity stream app.  Issue occurs on other Roku devices as well regardless of whether HDMI-based or Roku TV OS.  No changes to my network either, getting full speed in the tier I subscribe.

Anyone else having this issue?
