This is due to technical issues. The media group's press service announced this on Facebook.
"Media Group Ukraine channels ("Ukraine", "UFO TV", "Indigo TV") are temporarily operating in unencrypted mode on the Astra 4A satellite due to the breakdown of the main and backup signal delivery lines. Restoration work is underway. As soon as the malfunctions are eliminated, the channels will begin broadcasting in encrypted form", - the statement said.
