Good news everyone that had lost the Ultraflix App from their Samsung 4k TV's. I received just now a response from Ultraflix support indicating that a new updated app will be available to users to download on their sets by end of this week. I was offered an apology for the inconvenience and a refund offer for unused movies I had previously purchased. I responded that I was looking forward to the downloading the new revised ultraflix app for my set to continue viewing their movies. All is good!
