Restart on Android device

On FireTV I can simulate WMC restart by holding down the left direction or REW button to quickly get to the beginning of a recording. How can I simulate restart on the Android app? I can't hold down the -7s icon.

You can drag and drop the current position on the timeline to the beginning.

I tried that before posting. I assume by drag and drop you mean tap-and-hold the position vertical bar on the timeline and drag it to where I want it and release. The position bar is not responsive at all to my attempted moving. I don't think it's recognizing my touch.

Okay I will double check. I think it may be very sensitive about being tapped exactly on the purple area. I'll see if we can make it more responsive.
