Shopify Marketplace Connect

Despite having 24/7 customer service available via chat, I am yet to receive any resolution to the issues I am facing. The responses I get are limited to a single email per day, either requesting additional information or stating that I will be updated on the progress. The core issue is a SKU mismatch on all the items. If you are trying to run a serious e-commerce business, this platform may not meet your needs. I was informed that my case was forwarded to an engineering team that appears to be non-existent. very disappointed !
