Spectrum TV app won't open on Roku Streaming Stick or Streaming Stick+
The Spectrum TV app works fine on my TCL Roku TVs, and my phone, but it won't open on my new Roku Streaming Stick 3800 or my new Roku Streaming Stick+ 3810. After clicking on the Spectrum TV channel (app), it loads to the standard Spectrum logo blue screen for about 10 seconds, but then it just closes itself and takes me back to the purple Roku home screen every time. It never gets to the login screen or anything else...and there are no error messages. I've tried restarting Roku, unplugging Roku for minutes, factory reset Roku, and uninstall/reinstall Spectrum TV channel app multiple times. Every other channel app is working fine.
Roku software version 8.0.1 , build 4090. Spectrum TV version 4.8 ,build 2. I've already chatted with Roku support and Spectrum support but they couldn't fix it.
Any help or suggestions would be much appreciated.
