Blueprint in the Zoho CRM Mobile App does work but with a few limitations:
For now, the items (Attachments, Fields, Associated items, Checklists) within 'During' transitions will not be executed on the app.
Attachments : If the attachments are marked as mandatory, the corresponding transitions will not get executed.
Fields : With regard to fields, only if you have selected the respective module (for which you have setup the blueprint) as a field, it'll get executed. For example if you are configuring a Blueprint for Leads module and if you select Leads as one of the fields, it'll get executed, other modules selected as fields aren't supported yet.
Associated items : Inventory and Activities modules aren't supported.
Checklists : If you have added any checklists to the transitions, then they wouldn't get executed.
Zoho are addressing these limitations and are planning on resolving them in future updates.
