UX Enterprise sign in SSO

Hi,
Could you improve the login UX across all the UI? When my coworker sends a dropbox link that requires login, almost of the login screen doesn't have an enterprise user sign-in link. If we log in with our email, it took us somewhere (individual account?) and I believe it's not related to our enterprise account. I have to log out. I learned the workaround, I have to go to https://www.dropbox.com/sso and then log in. It takes me to the main page of dropbox. I have to close the browser window then open the link that my coworker gave me again. I have to do this every day when I interact with dropbox. There is one occasion I saw the SSO sign-in link is in the login page but most of the time, it's not there. The user experience is not consistent. Just in case you need to reach out, my email is 

[Removed as per Community Guidelines] I'm not sure if [Removed as per Community Guidelines] is my Dropbox ID for enterprise or individual account? This is the reason why I am confused?
