Safari Signs Me Out While Streaming

[tkmb]

I am using Safari 13.1.2, which uses Adobe Flash and I have it enabled.  If I open Safari, go to Xfinity Stream, and then open another tab in Safari, do anything etc, go back to stream, it refreshes after about 2 seconds and redirects me to sign in again. Spoke with Apple support.  Not a known issue.  As a course of troubleshooting, I tried streaming on Chrome and it does not do it and it only seems to be on Safari.  It also does not affect other streaming sites in Safari.  It is like it has to re-establish a connection with login info for a page/tab already running. This is really annoying and just started happening recently. I have tried everything from making sure content blockers are off, clearing history and cookies, turning on cross-website tracking, and nothing works.

not an answer to yoru question, but note that xfinity no longer uses adobe flash (only used it to verify the security of the HDMI HD video path).
