Anybody else have the problem where you fingers are so calloused that your iPad doesn't recognize it as a finger? Or you can't unlock your IPhone with your finger print? Or do a David Gilmoure like bend and then it makes your skin have almost like a flap that gets caught on all the other strings? Or catch hangnails on the strings? That hurts. But there's nothing I'd rather do than play. Lmk what struggles u guys have
