We have two Roku Sticks on two of our TVs. I do not know how the Express works in comparison to the Stick so what I will describe is how our TVs display when you turn them on using the Roku Sticks.
The Home screen displays a menu on the Left side of the screen starting with 'Home' and ending with 'Streaming Channels'. If you use the remote control, there is a purple cross shaped button that has 'OK' in the middle and arrows on each end of the cross pointing either up or down or to the right or the left. Using the 'down' button with the 'Home' selection of the Menu highlighted, you scroll down until you get to 'Settings' (You can also scroll up one selection from 'Home' to get to 'Settings' on my menu.) When 'Settings' is highlighted, you will see another menu on the Right side of the screen. Mine lists 'Network' down to 'System'. To access this network, use the 'Right' arrow on the purple cross to move to the menu on the right. This should highlight 'Network'. When you highlight 'Network', that menu slides to the left of the screen and a new menu opens on the right side of the screen showing all the options for the 'Network' settings. You use the down arrow to move down the Left menu to 'System' (or, on mine, I can also use the Up arrow and the menu will move to 'System'. When you get the menu selection to 'System', the menu options for the 'System' settings will display on the Right side of the screen. On my list of 'System' options, about half way down the list is 'System Update'. Use the Right arrow and scroll over to the menu on the Right to the 'About' selection. The menu will move to the Left again and a 'Gear' icon appears on my screen on the Right side. Use the Down arrow to move the highlight down the menu on the Left of the screen to highlight 'System Update' selection. The Right side of my screen shows a 'Download' icon with the date and time of the last time the Roku device checked for updates and the last time it was updated. Mine shows yesterday's date as that was when I updated my device software. If your device is showing an older date, you probably want to update. If you want to update your device, press the Right arrow again. My screen shows the 'Download' icon moved to the Left of the screen and on the Right of the screen is a bar that says 'Check now' and on my screen this bar is already highlighted. If it is not highlighted on your screen, move the selection using the arrows to get it highlighted and then press the 'OK' button to start the download of the update to your device. My screen displays a box that says the Roku device checks for updates automatically every day, but my device was not doing that as the date of the last update was several months back from yesterdays date before I did this manual update. When you click the 'OK' button, the system will do an update to the software and will restart when the new software is loaded. Depending on your internet connection this will take different amounts of time to download and restart, so just wait for it to finish (you will see a % completed display as it downloads). When mine completed, it started to display the "dancing Roku" screen. I hit the "Home" button on the remote and the regular starting menu appeared as usually displays when I hit the "Home" button. Then I selected the Spectrum App and clicked OK. The first time I did that after the update, the screen showed that it was reloading the Spectrum App (a little different display that usual) but then started the Spectrum App as usual and everything was fixed with the Guide and channel display according to my Spectrum subscription.
So I guess updating the software on the device and reloading the Spectrum app after the update, fixed the issue I was having. Hope it works for you.
