I am trying to use the Restricted User account feature of the tablet for blocking my son from accessing YouTube and certain other Apps. It has been working great for awhile, since he doesn't have the PIN to the main user or Guest account. Recently, I noticed he was on YouTube on the guest account of the tablet. I thought he had figured out the PIN so I changed it on the guest account. The next day I found the same thing! Turns out, after a recent update, when you try and log into the Guest account, it will ask you whether you want to continue using the account as is or reset it (before you type in the PIN). Choosing the reset option will reset the account to square one, remove the PIN, and allow full Guest account access. Deleting the Guest account anywhere on the tablet, still leaves the option to log into it from any profile that is logged in (including the restricted account) and allowing full guest access. I just preformed a factory reset but the "feature" of resetting the guest account still remains. Please help.
