abigail30 The Xfinity Stream error TVAPP-00100 indicates a communication breakdown or authorization timeout between your streaming device and Xfinity's servers. I would recommend restarting your Xfinity Gateway, or modem, and clear the cache for the Xfinity Stream app on your devices.

@abigail30 Are all the TVs the same make and models and what are they? Are you getting that error on other devices besides your TVs?

No, they are all different TVs. I have Sony, Toshiba and RCA
The error messages that comes up on the TVs say
Thank you for being a valued Xfinity customer. We have having trouble logging you into the app. Please try again later.
