Northern Baby Goods review for Etsy Integration ‑ DPL

Despite the fact that the description f this app claims “real time sync” of orders and inventory, this has never worked for me in real time. I sell on Etsy and Shopify and want this app to keep my inventory between the stores in sync so I don’t oversell a product. After reaching out I was told “ Every 10-15 minutes, our app syncs. We currently do not have live syncing, but we are working on it for the future. When you make changes in Shopify, syncing will take approximately 10-15 minutes, and if it takes longer, you are always free to contact us.” I have yet to receive a follow up response. Is this app straight up deceiving customers with their description that it syncs in real time? If I could give zero stars I could, and I will be following up with Shopify regarding their false advertising.
