This warning appears when Meta detects that some products (or their variants) which previously received ad impressions are no longer available for advertising.
It typically occurs in scenarios where:
The product or one of its variants has gone out of stock.
The product has been moved to draft/unpublished on your website.
The product is no longer part of the catalog being synced to Meta.
Even if a single variant of a product is unavailable (while others remain active), Meta may still trigger this warning if variants are passed individually to the catalog.
Why You’re Seeing This Warning
Meta keeps track of product impressions served to users. When a previously advertised product becomes unavailable, Meta flags it because:
“The audience that was shown this product ad earlier cannot be served the same ad again — since the product is no longer available.”
This is not an error from BigAtom, but a notification from Meta indicating that certain products are temporarily excluded from ads.
How to Resolve
Check product availability on your website:
Ensure the affected product(s) or variants are published and in stock.
Verify that your product feed or connected catalog reflects the correct availability status.
Re-sync your catalog with BigAtom (if applicable):
Trigger a manual sync to update product status on Meta.
Once the product becomes available again, the warning will automatically clear on Meta’s side.
Ignore the warning if products are intentionally unavailable:
If the products are permanently removed or discontinued, you can safely ignore this message — it doesn’t impact other active ads.
Key Takeaway
This message is informational and not a system-breaking error.
Your ads for active products will continue running normally.
The warning will automatically disappear once the unavailable products are back in stock and synced to Meta.
