I've tried to sign into my pureflix account and it tells me to pay for the subscription and when I got continue it says purchase made you can watch on your streaming channels
But it doesn't work it wants me to sign in I've talked to pureflix but they can't do anything since I went through Roku
Try a reset Settings/system/system restart
Hopefully it'll work.
They are responsible for the Channel they publish.
If they dont want to support it especially given that its a paid Channel
I'd say cancel it.
Did you sign in?
