So.. and update.. and a weird one..
I spent 40 minutes on the phone with a very helpful rep from CBS All Access. After doing the usual troubleshooting (resetting routers, clearing cache, etc .) we found something interesting. Older shows opened fine. Seemed to be an issue with the newer, more high resolution shows it seemed. Then, and here is the weird part, I noticed I had about 7 shows in the 'Continue watching' section. Interestingly, those shows opened without an issue. The tech and I were thinking maybe there is an underlying issue with Rokus and the number of shows you have in the 'Continue watching' section. So, I watched those and cleared them out. I then went and tried to open another show and what do you know, it launched.
I will say that I did get the error message one or 2 times, but at least I could watch something now.
The issue MAY be a combination of Roku's v9.2 and an update to the CBS app that may require more bandwidth/resources now. The fact that my older Roku device had NO issues until it updated to v9.2 indicates this loud and clear. I will continue troubleshooting and post my findings here. I just wanted to share the update
