No email history on m.zoho.com/crm

Hello,

I am using the web browser version of Zoho Mobile (through http://m.zoho.com/crm).
It works pretty well, but I miss the email history. I cannot see what emails were sent to the contact person.

I don't need to send or edit. I just need the view so I can see what was sent earlier.

Thanks !

Herbert
