  • When you are not signed into any of the accounts.
  • When you are signed into at least one of the MSFT/GitHub accounts.
  • When you are signed into both MSFT/GitHub accounts.
  • When you are signed in using multiple users in both accounts
  • Make sure the last used account for sync label is shown
• Test that Gear/Accounts menu shows Turning on Preferences Sync... item in all windows while the sync is being turned on. In addition Gear icon also shows the progress.
• Test that signing out from the account you are using for Sync from the accounts menu will turns off the sync.
• Test changing accounts to sync preferences works as expected. (Turn off and Turn on with different account).
