All About Me Boutique review for Retail Barcode Labels

We have been using this app for over 4 years and it has worked well for us. However, in the last month it has given us so many glitches. Shopify support can't help on this one. I've spent hours on this! It's randomly reassigning barcodes to products so when we scan an item at checkout it doesn't recognize it. Manufacture barcodes that we added so we could just scan the product aren't recognized anymore. we are having to manually lookup items at checkout or just redo barcodes on 100's of items. We are a small business and don't have time for this. Hopefully this will resolve itself soon because overall it's a great app.
