Yes, thanks Bobbie.
What we have tried:
* Removing app / restart, reinstall, restart. (several times)
* When this didn't work, we even switched to a different ROKU device we have in the house (newer iteration) with the exact same results.
* Watching online (PC / laptop) works fine. We can stream from my laptop, but it uses a ton of resources, and I'm on my laptop quite a bit for work.
......when it did not work with 2 separate ROKU devices, we began to suspect a spat between our local Spectrum Market, and Roku. We are really at a loss, because as I said - it works online after authentication.
