so I've been getting apps and stuff from market and then Google store with both my LG Optimus 3d and galaxy tab 10.1 for just over one year. the other day I noticed that the LG phone was no longer listed in play store under my devices. now I find I can't down load any apps but I can log on with the phone and browse apps. The Tablet is listed with all its apps. Anyone know what I've done wrong?
