I also have a Tab4 in the house. but just picked up a new Tab Pro. but when I launch the WatchOn for the new device it says unable to retrieve data from the server error. try again later. the Tab4 is on vacation with its owner so I cannot try that to verify if it is the service or the tablet giving the issue. its new so it has never been used as a tv remote like the other tab4 was used. is this a issue anyone has come across?
