What it means
The availability in the feed should reflect what a customer can actually buy on the landing page, including the selected variant.
How to fix it yourself
- Check the exact variant and its stock state on the public landing page.
- Compare the site's stock status with the feed value and the schedule of the system that generates the feed.
- Correct inventory sync, variant mapping or caching issues at the source, then refresh the feed.
- Check country and local inventory rules if availability differs by region.
