It's really hard to customize ZOHO CRM to a business workflow when you cannot use Multi Lookup fields in modules as they don't show up in the mobile app.  We don't use the mobile app as a convenience, it is what we use everyday in the field. We use the desktop version while not in the field to do estimates and add customer/job information to ZOHO but, when we are in the field, we need access to all that data in the mobile app. We are a construction business and I need all the information while on the desktop as well as my mobile app so I can conduct business. I am having to build my app with limitations with hope that ZOHO someday may add something, then I will have to go back, rearrange all my customizations to work with a new feature and everyone has to readjust their normal daily routines to accommodate this. I don't understand why there are fields available that aren't available in both the desktop and mobile version.
