Thanks for the insight. I disabled all my extensions one by one. It turns out it was the Private Internet Access Chrome Extension. Even though the VPN was not turned on, it apparently does a number of things, including Blocking Flash when installed. It has settings where I was able to turn off that option. It now works.
Also, it appears that Chrome and FF both work without issues now. No more camera feeds immediately dropping out and they are staying connected. So I’m not sure what changed, but it is working as expected now. Thanks for the help on this!
