My Netflix suddenly stopped working/performing

Not sure if this is related, but the other day late at night a RUM micro site app appeared on my Home Screen. It was where my Netflix app is usually displayed on my Home Screen (first). I went to options and removed it. I can’t recall if I actually clicked on the app or not. 

The next morning, and continuing since then, Netflix won’t work on my Roku. The RUM app is no longer there, but Netflix just won’t work. 

When clicking on Netflix I either get a black page, or with patience my queue comes on but only one preview displays on the Home Screen… nothing else appears, there are no images; it’s just black and gray and the title of the category/row. As you keep scrolling down, it’s the same thing over and over. But oddly, when clicking on a movie (hitting enter on remote) whatever I selected plays fine. The problem is, I have no idea what I am selecting because THERE ARE NO TITLES and the Home Screen is black. It’s hit or miss on my other Roku in another room.  It either won’t open at all and I get an error message NW-8-20 (or something like that). Or it’s black boxes and not titles just like the above. 

 

These are the things I have tried to remedy this:

I reset my Netflix password.

I updated the Netflix app.

I uninstalled and reinstalled the Netflix app.

I have unplugged the Roku stick waited a couple minutes and replugged in.

I did system restart from menu 

I went to settings and manually checked for update. 

Nothing is working - still - it very frustrating. I should also note that our other Roku in another room is also giving an error message when Netflix is clicked.

What’s going on? How do I fix this? Why is my Netflix Home Screen going wack?
Is this somehow connected to that weird app that appeared? What the heck was the app anyways?
