If that doesn't work, the article suggests disabling Google Play Store:
"If that doesn┤ work, you can try disabling the Google Play Store app
entirely, but that┬ going to be inconvenient."
Note that I don't have any Google Account on my phone and haven't had one
for months and everything works just fine since you can sideload all Google
Play Store apps directly off the Google Play Store by a variety of means.
If you wish to remove your Google Play account:
o Settings > 3dot > Tab View > General > Accounts & sync
o Accounts > Google > {select your account} > 3dot > Remove account
