Over the past 2 days, whenever I try to download/install an APP via the Play Store/Market app on my TABLET, the app thinks for a while and then displays this error message:
Authentication is required. You need to sign into your Google Account.
But I am indeed signed into my Google account, and as seen if I open the menu in the Market app and click the "Accounts" button.
Does anyone know how I can solve this issue?
thank you in advance!
