I started having the same problem when I bought a brand new Amazon Fire 8 HD tablet. Pandora will not launch but only displays "An unexpected error has occurred. Please try again". nothing has worked. Uninstall and reinstall.
Then, I bought a brand new Roku Express 4k player and every app works except Pandora. I've had to start using Amazon music on both devices and may switch to Spotify but I really don't want to. I like Pandora.
My Roku OS version is: 13.0.0, build 24056-E4
Pandora version is: 6.5, build 0
My Amazon Fire HD 8 - 12th Generation tablet is running: Fire OS 8.3.2.3
Pandora version is: 2401-1
When attempting to launch Pandora on the Fire HD the Pandora logo beats like a heartbeat and then gives a popup saying "Waining for connection. Try again?" Trying again never works and every other app, including browsers, work fine and browse the web.
Help!
