Zoho CRM Mobile App not syncing accurately

Zoho CRM Mobile App not syncing accurately

My tasks on my laptop do not match the tasks on my iphone using Zoho Mobile CRM app.  For example, I show 21 tasks for today on my laptop and only 14 on my iphone.  I have tried the suggestion of "resent application" and it doesn't solve the problem. 
 
I have emailed support@zohomobile.com and a very frustrated with the response - you offer a solution and seem to close the ticket even if it doesn't work. 
 
Please help resolve this issue.
 
Thank you.
