Shopify Marketplace Connect

After more than four years of happily using Marketplace Connect, it's just astounding that after it broke, developers were unable ot fix it in over a month. Long story short, Shopify Marketplace Connect's eBay integration ceased to work last month, and despite week after week of promises from the developer that it would be back, it remains broken with no end in sight, so I have since pulled the plug and moved on.
