Certify'em and Multiple Sign-ins

Methods to work around multiple sign-in issues:

1. Click "Sign out of all accounts" in the menu shown above.  Then, sign-in again with only the account you will be using with Certify'em. This will be the same account you want certificates emailed from, as well as the email address associated with your paid subscription (if you have one). Then use Certify'em in your Google Form.
   
   

2. Open your Google Form in a private browsing or incognito window. Once there, sign-in with only the account you will be using with Certify'em. This will be the same account you want certificates emails from, as well as the email address associated with your paid subscription (if you have one). Then use Certify'em in your Google Form.
   Note: Recent changes to Google Chrome (related to cookies) may prevent you from selecting a certificate template while in incognito mode. If this happens, you may need to use a different browser (i.e. Safari, Firefox).
   
   

3. If using Google Chrome, create separate "Chrome profiles" for each of your accounts.  Sign-in to only one Google account per-profile (i.e. do not use the multiple sign-in feature). When you need to access a different account, just switch profiles.
   
   This is general best practice when you have multiple accounts, even if you aren't using Add-ons, as it keeps separate your bookmarks, browser history, cookies, etc.
   
   For this last method, it's important that you don't mix-up the concept of Chrome profiles with Google multi sign-in, which can look similar. See the illustration below to understand the difference.
