Yes! This is a feature so many users requested that it's now available. The Notify next user with setting allows you to choose how a user is informed that the App is ready for their input.
You'll make this choice on the Workflow page, which you can get to by navigating to your Apps page and clicking on the name of the App you want to configure this for. Then scroll down to the Features area and select Workflow.
When configuring your handoffs in creating a Workflow you have the option of configuring how the recipient of the handoff should be notified. There are three available options:
Each handoff can be configured differently so you can ensure that the user being assigned the handoff will get the proper notification. The assigned user will then need to log in to GoCanvas on their device (Android, iOS, or Windows desktop/tablet) and synchronize to access the handoff and complete the work necessary.
