I generally am doing something else with my phone in front of me and just keep hitting the videos over and over. There seems to be days when it will let you push it all the way, reloading over and over when it claims there are no more to be had at the moment. Can take hours but what else does this old man have to do? Sex? LOL. Not anymore. hahaha
Those are the big dollar days and when you strike that vein, keep digging!
