Zoho Creator Application - New User Not able to access the application


In Zoho Creator, The newly added user not able to access the " Added Application" - User has received the Invitation Email, but while clicking "confirm Account" in the invitation Email, the following error message has appeared.

"Sorry! you cannot accept this invitation now.

We see that you have signed in as  <<UserEmailID>> Please sign out and try again"

even after signout and sign in - It is NOT working.

Did anyone else faced this issue ? What is the resolution / workaround for this.

Thanks in advance.
