Will not register any shots. Have indoor setup. Blinks green, I hit the ball, nothing happens, it blinks white. I have to turn it off and back on to get the green blinking light back just to go though the same motions over and over again. Even had a rapid white flashing thing goin on for a while. Updated on express, that did nothing. Tried holding button for 30 seconds, did nothing. Has anyone heard any good fix on this yet?
