Current catalog checks surfaced by Atlios, with what triggers each issue and what fix path is available.

product, variant, image, or cross-catalog pattern needs review.Each check has a default severity. Store settings can change which checks run
and how severe they appear.
This page describes the current supported checks and fix paths. The app shows
the exact action available for the issue you open.
Triggers when explains why Atlios creates the issue.
Default severity is the built-in priority before store-specific changes.
Fix path explains what Atlios can help with.
No auto-fix when explains when the issue needs manual review or a scan
after a manual change.

integration, not from a catalog scan.
Google reports them and Atlios shows them in the same inbox. Most use Open
in GMC, where you resolve the issue in Google; a few have a guided fix that
updates the matching Shopify field. After any fix, the issue stays in
Verifying until the next sync confirms Google cleared it.

the issue as critical. Any GMC issue type not listed here still appears,
with Google’s original wording.
