Thanks for bringing this to our attention, @haung38.
We'd like to understand this better. Can you specify what channels or shows are not streaming? When did you start having this issue? Lastly, have you already started restarting your device through Settings > System > Power (skip if option unavailable) > Restart?
Please keep us updated.
