On yourdesktop, you can sync Gmail very easily. Just go to the Settings and then click
'Accounts Email & App' and then click on 'Add an Account' and your Google
account. Then, enter your email address and password and review the
permissions, then click 'Allow' followed by a click on 'Done.' However, if the
Gmail app not syncing with desktop, you need to check the sync settings in the Gmail app tomake sure they're turned on. This should, of course, be enabled by default, but
anything can happen. It's possible that you unintentionally turned it off. Make
sure Sync Gmail is enabled under 'Data use.'
