Check our YouTube tutorial on How to Bundle Scan
To bundle, you'll need to make sure the destination you're sending to has "Bundle Scans" turned ON:
Then, on each page you'd like to bundle, mark the same symbol and scan sequentially.
Or, if you do not mark any symbols, you will be asked where to send your bundle once you're done scanning.
When Bundle Scans are turned ON, Auto-Send is OFF, so you will need to tap "Next" after scanning all the pages in your bundle and then tap "Send" after reviewing.
