Why can't i watch live streaming on my galaxy tab s2

[AC Question]

I bought the tab on the 19th of Nov and i watched a match - live streaming-on it. The following day there was an update. Today when i tried to watch a match - live streaming- i kept getting a message that my tab is outdated and i need to update the software in order to watch, although my tab is already updated to the latest version.
So what shall i do to fix this problem
