KRE Prime review for TikTok

I'm extremely disappointed in the TikTok Shop app. I was excited when the app first came out. it's seem to be working for the first month or so, it's was great but it worked. Now, I'm uninstalling the app because it's not working and I can't get any support. I can't sync my products, inventories from Shopify to TikTok shop and I can't sync my order from TikTok shop to Shopify. It's has been a nightmare, so I will be going back to the previously app I was using. I have submitted over 10 support tickets and receive zero support. They closed the tickets and gave me the running around respond, like AI. Having zero customer support for an unstable app is the worst.
