My Roku tv would show the loading screen when launching apps... then I read about clearing the cache and apps now open without even displaying the loading message.
To clear cache on Roku, first, you need to pair your Roku Remote with your device. Remove cache form Roku is done by using the Roku remote button. From the Roku Home screen, select the Home menu option.
Then press the following remote buttons consecutively.
Press the Home buttons 5 times.
Press the Up button.
Press the Rewind button 2 times.
Press Fast Forward 2 times.
After that, you have to wait for 15 to 30 seconds, the Roku device will clear the cache and junk files from the device and instantly restart your Roku streaming device.
