Products that are “no longer available” on AliExpress still appear as “in stock” on storefront

Some products I was selling now show as “no longer available” on AliExpress, but still appear in my store as in-stock (and therefore presents an issue where users could be purchasing products that are not available).

Is there a way to ensure that:
1. The app automatically updates these products (the same way it updates pricing changes?)
2. I am notified when a product suddenly becomes unavailable on AliExpress (the same way I am updated when a price changes)?

Thanks!
