Automatically transferred from Docs to Workdrive?

Automatically transferred from Docs to Workdrive?

Dear all,

My colleagues want me to use Docs to access to their files. However, my attempt to access to Docs has never been successful.

It is always Workdrive I end up.
My colleagues insist that they authorized my account to access to Docs, but the log-in always results in Workdrive.

 - I use the single Zoho account for laptop pc and smart-phone.
 - My Zoho Home never shows the Docs icon.
 - Clicking the URL of Docs leads me to Workdrive every time.

Could you please advise me how to use Docs properly?
