I cannot switch back in time with SmartIPTV on my fireTVStick. It is possible with SmartIPTV on my mobile and with webplayer in Browser, but not with  SmartIPTV on my fireTVStick or on my Samsung (Tizen). It worked on a friends SmartIPTV on fireTVStick, but on my it isn't working.

The support says, thework on the server, but why does it work in web, on mobile and not on firetv? we have all the same server (6)
