This is the exact same issue me and others are having, being unable to load the Pandora app on the Roku Express 4K model player. Every I click the app I get an error message and it won't work. Roku tells us to do the same troubleshooting steps that they are saying here for Vudu. The steps don't work, then the Roku moderator tried to blame it on Pandora despite the fact that Pandora works perfectly on every other Roku model I own other than the Express 4K.
Now Roku is doing the same thing here, trying to blame it on Vudu when the original poster says Vudu works fine on all his/her other devices. Roku has no solutions to any problems like this, the moderators have no ability to help other than copying and pasting the same steps that don't work.
When that fails Roku then tries to blame it on the channel provider. If you contact the channel provider they will turn around and blame it on Roku. Each company points the finger at the other and nobody takes responsibility and the customer receives no fix for their problem.
That is exactly what is going on here! It's pathetic! Roku customers deserve real solutions from Roku when things like this don't work.
