Workflows currently stall (=die) if a file is meant to be moved following a task assignment, where the assignee edits the file and "Marks as complete" without having closed the file's tab. This can happen quite commonly: a user is asked to input edits into a file, so they open the file in the relevant Office online app (eg Excel online), and when they're done editing, if they forget to close the Excel online tab in their browser before going back to the BOX preview tab where they click on "Mark as Complete", then the workflow stalls. It would be vastly better if, instead of stalling, BOX/Relay could rather "pause" the workflow and send an email notification to the assignee and/or the workflow owner, asking them to pls close the problematic tab/file, and ideally providing a button in the email that they can click to confirm when they have done it. This can trigger the workflow to try resuming. This basic concept should be applicable in various instances, thus markedly reducing the number of failed workflows, and making the system vastly more robust (which will also increase confidence and adoption...)
