In Anvl you can edit your workflows until they are compete. If you accidentally start a workflow that is not necessary, they are easy to delete in the mobile app.

When in the workflow you'd like to delete, find and click the "Keep In Progress" or "Close" option in the corner of their screen.

This will take you to the work folder. There, you can swipe left to delete the accidental workflow. Keep in mind that completed workflows or workflows marked "Incomplete" cannot be deleted.

Workflows also may "time-out" if they are open for a long period of time. Typically this time period is 12-72 hours. Workflows that time-out will be marked as "Incomplete."

The image below shows what the screen will look like when you delete when you delete a workflow.
