Android device contacts when sending emails from Zoho app

Android device contacts when sending emails from Zoho app

HI,

When creating an email in Zoho Mail Android app, the app never suggests any of the email addresses of the contacts stored on my device - as opposed to the ones already in Zoho.  How can I get the app to use the device contact list?

Secondly, when I do go to the device list in the app (press the + next to the "to" field), the device list is very very slow to load - in the order of tens of seconds, and the list is totally linear - i.e. contacts that I have in a CalDAV addressbook and LinkedIn are not combined, even though the email addresses are duplicates.  How can I get the app to merge the users?

Thanks

Alan
