I'm wondering if you could help me. I have a Roku Streaming Stick 4K connected to my Samsung tv. I followed the instructions on how to add a flash drive so I can pause live tv, but when I install a flash drive into a USB port on my tv, Roku doesn't format the flash drive. Technology is going too fast and it's hard to keep up. Am I not doing it right? I'm disabled because of a TBI that put me in a coma for 16 days. I follow the instructions, but nothing happens and maybe you could tell me what I am doing wrong. I appreciate your help
