When an item is scanned at POS and has multiple price if there is a big queue and you are scanning and billing products very fast then when you scan an item and it has multiple price and if one is not looking then when you scan second item then you skip one item in billing.
Option 1 - there should be a different alert sound when an item has a pop up compared to the sound which comes when we scan an item
Option 2 - It should be the way it was in version 10 that first one screen pop-ups and then second one with multiple prices that way you can not skip an item
