The latch should not have to be beaten !!
My latch will only release when all of the weight is off of the hitch. If it doesn't want to release then, I will pull the truck forward slightly, to get the hitch ball to the front of the cup.
Someone mentioned that they are afraid of damaging the tongue jack by moving forward. If that is the case, block the trailer wheels, get the jack off of the ground before pulling the TV forward.
I presume this is a "given", but make sure the WDH bars are unhooked before trying to release the latch.
Some couplers have an adjustment on how tight the pawls grip the ball......an adjustment may help.
Unless the ball tilt is really severe, that should not affect the latch release. The ball tilt is important to the weight distributing, and should not be adjusted just to make the latch easy to release. I have my head assembly tilted back almost to the stop, and I can still get the latch to release with my above statements:
