Duplicate SKU Sync Master

5/2025 UPDATE: Original issue was fixed from 2021, but now I have a new issue where the app is removing x2 the amount of items being sold. Example, I stocked an item at 15 pcs. 4 were sold. It synced the skus to have only 7 left in stock. I have to keep babysitting my sales again.

i upgraded from the free plan and now i am having issues with inventory. products that have been out of stock for weeks magically have new inventory, resulting in oversold products. Its a pain, especially when dealing with TikTok Shop's cancellation policies
