Yep, a few times I've ended up with something that hadn't scanned. A bunch of other times I accidentally scanned something twice without realising. Their app was bad at registering whether something had scanned or not; you would scan something again, and then later it would register the first scan. One time they did a random check on my bag and found one item that hadn't scanned. They didn't accuse me of theft, but they did block me using their self scan app. This was actually a blessing, as their app was so frustrating and unreliable shopping became more pleasant.
