2to3 wks.ago,My husband's computer wasn't working. So I let him use my tablet. Since then we've been receiving each other's emails etc. So he changed his password to try and fix the problem,but now it's not allowing me to sign in to YouTube etc. Because it tells me to sign in, but shows his Gmail account and asks for his password!!  What is up w/that??? Please help!!  Sincerely, Mary [email protected]  Thanks!!
