Why is DirecTV login not working on my Roku TV?

Same issue here. I can log in just fine on my Amazon Firestick and on my mobile phone, but none of my roku sticks will allow me to sign in to Directv Stream. It just loops back to the log in page. I too have tried getting help with Direct TV Stream support and they were not able to give me any answers. Sounds like this is a common issue though. Really hoping someone has a solution. If not, I may have to replace all of my Roku devices with Firesticks. Such a waste of money. :(
