A major draw back in the TuneIn app for windows phone is the inability for the listener to use the fast forward or backward functions when listening to a radio podcast, one day I started listening to an hour and half podcast, then after 40 minutes I stopped it, the next day when I tried to go back to the point where I stopped it I discovered that I have to listen to show from the beginning because the fast forward and backward functions are not enabled, I tried with several other podcasts from different radio shows and the functions are still not enabled in all cases. TunIn users in IOS and Android systems does not face this problem at all.
