Making sure all iPads are synced (ie some are offline or not synced at the moment that new flow sheets are created) avoids duplicate sheets being created for a patient.
To ensure this happens, go into settings app on iPad, then go to 'General' > 'Display & Brightness' > 'Auto-Lock'.
And set it to '10 Minutes'.
Please avoid turning off Smart Flow app or switching to another app. With the Auto-lock set to 10 minutes, and staying on the Smart Flow app, Smart Flow will be synced pretty much all of the time (due to syncing with every action that happens on that particular iPad, or every 25 seconds automatically if iPad is idle).
