I've noticed the following bug a few times. Let's say you've just completed a POG fill for that new sales plan you just set. After completing it, you go to scan to do some more work. Instead of showing you the information for the item you scanned, it shows you the info for a completely different item. You can scan the item again, it shows you info for yet a different item. You scan again, and it shows you the info for a third item. You notice that the items it's showing your info for look familiar. Lo and behold, every time you scan, it shows you the info for an item that was in your recently completed POG pull.
You must completely close out, and reopen myDay to get scan to function properly again. Talk about crossed wires.
