M2E Is not tracking database quantity changes

[tomstrangwood 0]

So, First time trying to actually do this. I remember in Magento 1 there was an option specifically to track database changes. 
I cannot find it in Magneto 2 though. From what i can see it's no longer there anymore. 

I have changed some test quantities to 0 though and waited for the cron to run. Those products stay active in M2E with the incorrect quantity. Even though the product card does have the correct quantity. 

Any ideas at all? 

Thanks.

M2E guys recommend setting up programmatical models instead of enabling the Track Direct DB changes tool. It will slow down synchronization of a large inventory. But yeah, the feature is now located in a different place. It's in Amazon or eBay - Health status - Developers area - Direct db changes.
