Soul Flow Apparel review for TikTok

I work in I.T. full time and I can't figure out this stupid app. First once I connected my Shopify to Tiktok it started trying to sync my whole product list. I had no say what so ever. So of course you start getting sync errors when it's trying to add over 1000 items at once without you even setting anything up. So after handling that I created a template to test out. Created it and then its not even an option when trying to sync a product. I can see them in templates setting, but nothing shows up when editing the products. Now I can't even add a product without receiving some type of error, and no customer service whatsoever.
