Zoho Project - Android App

Zoho Project - Android App

I have a user who is an admin.
She is not able to see all task that we created in the Task section on the Adroid App.
That task section only show her 2-3 task.
She need to uninstall the App, and retinstall to get the new task added.

Please tell me how should I get this issue solved in a correct way?
