Fetch_stock.json not updating inventory quantities suddenly

It seems that fetch_stock.json isn’t being processed for a few days now. If any Shopify staff could take a look that would be lovely. I can share our callback URL if a Shopify staff requests it in private.

I have a Request trace ID in the headers. Not sure if it’s needed.

The fetch_stock.json callback lands on my server. The server responds with a 200 message within 3 seconds. This was working for quite some time, but suddenly the values aren’t being propagated into our store.

Some examples:

Product Variant ID: 41733536219295

Product Variant SKU: 8720199139092

Quantity in fetch_stock.json: 121

Quantity in Shopify: 23

Quantity committed in Shopify: 4

Why is it not updating to 117 in Shopify?

So… I guess I won’t get any Staff to help me out here. I was directed here by reaching out to support.
