Horrible. It does not work as expected at all. Horrible support. Wouldn't recommend it. It just creates more mess. EDITED BELOW AS THE RESPONSE TO THE DEVELOPER WHO JUST LIED AGAIN! Hi, 1) you have NEVER understood the issue. You have caused multiple issues and damages, including money lost. 2) I'm a SW developer myself and it's best practice to build the app as follows: 1. development, 2. testing, 3. production, 4. maintenance. You have completely skipped testing and you have released your buggy app into the production phase. On top of that, you even charge us as clients for it. All Shopify clients.This is poor development and shady practice just to get money from your customer with not even 20% baked product. 3) Spreading a lie on the Shopify marketplace that you have issued me a credit? You did it because you have removed our products from Vinted that were topped up without any legitimate reason, so basically you just refunded us money for what we have lost thanks to you. 4) My language? I told you and explained to you probably 20x what the issue was, what you caused and you always came back to us with a sort of non sense asnwer. NO SOLUTION. So you should educate yourselves on what product development means, how customer support works and stop charging customers for something that simply does not work at all. If it's just 1 bug but to name a few - incorrect prooduct size synced to Vinted, incorect product category synced to Vinted, you do not support currency so we almost lost more money as you pushed Shopify products as 49 CZK instead of 49 AUD which is 10x less, you missmatched Shopify products and its SKUs causing us losing all products on Vinted that were topped up so lost money and I can go on if you want. You should accept what you caused, apologise us and correct you answer and xif up your bug. Instead you are spreading here a lie that just shows who you are and how you operate. JUST RUN FROM THIS DEVELOPER!
