Task sync problem of activesync with zoho account (lg g3 beat)

Task sync problem of activesync with zoho account (lg g3 beat)

Hello,

I am trying to sync my tasks with my zoho account. I have added my zoho exchange account to my android LG g3 Beat phone. Calendar and contacts are syncing perfect but when I switch to tasks app, my zoho account doesn't show on account list. When I try to add again, it says this account already added.

Does zoho tasks support task syncing through exchange?

Tasks are enabled on my user details in zoho account settings by the way.

Thanks for your support in advance.
