When I open the app the screen is blank, an error message pops up saying "COULD NOT FIND USER". I have uninstalled/reinstalled MULTIPLE TIMES & cleared out the cache & storage. I have successfully been using Just Play for over a month, so I don't know why all of the sudden I am getting an error code and no option to interact with the app whatsoever. I have emailed customer service 5 times and NO response. I need help getting this issue fixed!
