HBO Max App on Screeneo U5 bug

I’ve downloaded HBO Max on the U5 and for some reason it has this weird glitch where if I play a show, it goes through the episode recap, and then it has this weird picture malfunction where it shows a large green box at the bottom and two smaller images at the top that plays the show.

I hit the back button and play episode again and then the image is completely fine like nothing happened. This only happens with the HBO Max app. It doesn’t happen with Prime, Apple TV, Hulu, Paramount+, or YouTube. I play HBO Max through my Xfinity (Cable) box that is connected to the U5 and that works just fine.

Also, does anyone know when Netflix will work on the U5?
