Proper technique of dashing back from holding block.

WayWorn2525

I've been trying to figure out how to dash back from a holding block sucessfully.
I'll be holding block in trying to get the defender to throw a heavy, but when I try to swipe back it's still holds block.
Should I be lifting my thumb slightly off the screen and swipe back or just keep the thumb on the screen and swipe back without lifting the thumb off?

Are you holding block on the left side of the screen? That's not a normal thing, you can swipe back from holding block and it should backdash immediately. Maybe a technical issue
