I finally had some success. Figures it's right after posting this. Anyways looks like I had to detach the new google account via https://myaccount.google.com/permissions and it's now providing me a choice at lucid chart login!

Hi Clarence

Thanks for posting on the community and for finding this workaround. For future users with this question you can detach the new google account via https://myaccount.google.com/permissions which will allow you to set up a new Lucidchart account with Google. 

If you would like to change the email on your account you can make this change through your User Settings page. For more information please view this Account Settings article.

Last if you have any other questions or run into any issues please reach out by either commenting on this thread or filling out this Support form to contact Lucidchart support directly. Thanks!

Hi Clarence

Thanks for getting back with this solution! I am going to post it in the official comment for future users! 

Thank you again!
