Google sign-in problems

• The Google window does not open (web). Allow pop-ups for the Carib Code site and try again.
• The app shows “Your browser opened” but nothing happens. Finish signing in in the browser window, then return to the app. The sign-in code lasts 10 minutes; start again if it expired.
• “User not found”. That message is shown for accounts that are not allowed in the app, such as administrator accounts.
