Zoho CRM MOBILE has never worked for us

Hi, we reported this issue from our blackberry app, and never had it resolved.  so we cancelled that license.
Now today, I try to go here:  https://mobile.zoho.com/crm 
and get the error:
Unable to load Today's Tasks
Any mobile says unable to load data for any of our users.
Can you please look into this?
