    RandomDude66613, Oct 4, 2018 :
    Noticed that words are not syncing in gboard, went into settings and noticed that option "Sync learned words" is off and gray and can't be turned on, tried uninstalling update via Play Store, installing different versions of app from Apkmirror, rebooting, clearing cache... Now the sync option if completely gone... Anyone had same issue and know the solution?
