When is a unified calendar coming to Zoho?

When is a unified calendar coming to Zoho?

Hi,

I thought the latest update to ZB would bring a unified calendar across all apps (except crm for now). But to my disappointment this is not the case. They all still do not talk to each other. Is a unified calendar still planned. Did it get delayed? I know we are a couple of months from SSO in CRM but I thought the unified calendar would happen before that on all of the other ZoHo apps.

Thanks
