I can't sign in: Unable to sign you in because there is a personal Grammarly account associated with your work email address

If you encounter this message when trying to sign in to your Grammarly Business account, it means that you might have used your work email to create another Grammarly account for personal use. Each email address can be connected with only one Grammarly account. 

For you to successfully join your team’s Grammarly Business subscription with your work email address, we suggest the following:

1. Change the email address associated with your personal account. For detailed instructions, see this article.
2. Try signing in to Grammarly using SSO to create your work account.
