Proper Gnar review for WC Fulfillment Print on Demand

App used to be good, but is horrible now. Items are taking over 2 months to ship if they even ship at all. If they are shipped, they sit at the post office in the same spot for over a month. I'm not sure if my customers will ever receive their product, and it's making my business look bad and costing me money in refunds. I have tried the chat function and now they have completely stopped replying. I have emailed with no response. I have tried to post in the group, but they denied my post, probably because it's negative on them I'm looking for answers. DO NOT USE THIS APP!
