The Interacting Flows feature allows you to view all the flows that either Create, Update, or Comment on an Item in each App regardless of what Workspace that flow belongs to.
Note: This is a good way to help diagnose flows that continuously loop through an action that eats up your hourly limit, or to help you navigate apps that have relating flows.
To use this, select your App and click on the cog wheel beside the Add New button. This will give you the following dropdown - select Interacting Flows.
A pop up window will appear showing the list of flows that interact with this App. The last parenthesis on the flow name will display the App that flow belongs to.
From here, you can click on any flow and it will take you to the flow in the Flow Tree.
