You could try an internet search for the Play Store apk file to see if you can locate a site that your tablet will allow you to download
If your tablet will not allow you to download the Play Store the only option you may have is to re set the tablet to factory defaults but you would lose all data and have to re download the apps
Thank you bertrum that’s we have decided to do. Hopefully it will appear back after a reset. She is going to take off all photos then do it.. But strange thing is she tried to sign into her google account and was declined we tried looking into other things and found another google account with a foreign name but using her email address. Could she have been hacked in some way? Hope reset works for her. I use apple device so could not help much.
Thank you again Bertrum it is the correct password she has it written in a book since she set it up. Something strange going on have sent her your link to try thanks
