I have the same problem as everyone else except I didn’t sign up for GCP until January of 2021. It worked the very first time and then stopped. I contacted GCP and they suggested what others have mentioned: remove app; reboot system; add app back on. It did not fix my problem. I can access my GCP account fine from a computer. Very frustrating and trying to get support from Roku is equally frustrating.
Easier workaround (for me) is to restart the Roku device.
I have found (for me) a much better work-around then reinstalling the channel (app). It is to restart the Roku device and then go to the Great Courses Plus app. The Roku can be reset by going into the Roku Settings, then System, then System Restart. On my Roku Ultra it doesn't take long to restart.
I just recently subscribed to Great Courses Plus, and still see this problem, as of Feb 2021. So of course I should have the latest version of the Great Courses Plus channel (app). I have seen this on multiple Roku devices (Ultras). I had previously used Great Course (NOT Plus) which is a different Roku channel (app), and I don't recall having this problem.
To add a little detail, here is what I experience. The Great Courses Plus channel (app) will come up, and I get the spinning icon. Sometimes, I can access the "category" menu and find the course I want to view, and it will work. But other menus, such as the "watch list" menu, just hang (spinning icon). I have also seen cases where, after a few minutes, things start to work.
I have reported this to Roku, and mentioned that I cannot recommend the Great Courses Plus service for people using Roku.
Attempted to open the Wondrium channel and got a response saying it needed to be updated before it would open and was taken back to the Home page when I clicked the "OK" button.
Did the update in accordance to instructions by Roku, restarted and attempted to open channel again, received the same notice that it needed to be updated before it would open and was, again taken back to the Home Page when I clicked the "OK" button.
I then removed the channel, rebooted the Roku, added the channel and had the exact same response when attempting to open the channel, with the same results when clicking the "OK" button
At that point I checked and updated the actual Roku, rebooted, attempted to open the channel and received the same notification with the same results when clicking the "OK" button.
I then did a "factory reset", reloaded the channel and once again, for the fifth time received the EXACT SAME RESPONSE!!!
So, as I said, Roku seems to have a problem with that channel as I am fully able to open it on ALL other platforms in my house.
The Great Courses Plus has just rebranded to Wondrium and now I am unable to access it - I keep getting the same message that the system needs to be updated however, my ROKU is currently up to date and I can access it on all of my devices except Roku - how can I fix this? thanks
For more information about that channel's features and functionality, you'll want to contact Wondrium support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
Am having same problem. Using a Roku TV 7120X Software 10.0.0 build 4195-30. Hitting icon tells me about my subscription but clicking to site gives me a log in page rather than the site. worked fine when it was Great Courses a week or so ago
We would recommend removing the channel then adding it back in. To ensure the process is successful, follow the steps below making sure you restart your Roku device before adding the channel again.
Remove the channel: Highlight the channel tile on your home screen and press the Star button to open the options menu. Select Remove channel and confirm.
Note: If you are removing a subscription channel billed to your Roku account, you must cancel the subscription before you see the Remove channel option. For help identifying this type of subscription channel, read the detailed article about removing a channel.
Restart your Roku device: If it is inconvenient to reach the power cord to unplug your Roku device, you can restart the device from the settings menu. Go to Settings > System > System restart > Restart.
Re-install the channel: After your Roku device restarts, visit the Roku Channel Store and add the channel again.
Note: If you are adding a subscription channel billed to your Roku account, you will need to resubscribe.
If you are still unable to access one channel after attempting the suggestions above, other channels play fine, contact the channel provider's customer support team to report the issue and get help.
