The App freezes when a replacement is needed or a refund is requested. Especially if there is more than 1 item not found. I spent over 3 hours on 1 batch!!! The app freezes glitches and kills my battery even at 100% . My Customer was understanding thankfully. The app freezing is bad for customer service. It also makes me not want to work. 3 + hours for 1 batch is not worth $15. I love this app but if issue continues I will deactivate. This is the 2nd time it happens.
