Same here, the 'progress' bar is filled with orange and the timers are missing as well.
App v2.20.2 on a 2017 49mu6200.
I am having the same problem, model UE49MU7070. Have done a factory reset as suggested by Samsung and updated the app as suggested by NowTV. Used to work fine until the TV updated itself but now no rewind or fast forward.
I am having the same problem so frustrating p. I have a 55mu6100 too. Hope it's fixed soon!!
Same problem with my one day old QE49Q7F.
Same problem here. Model UE65MU8000
