# How your catalog stays current

> The two ways Atlios keeps your issues up to date: scheduled scans and live product changes.

Atlios keeps your issues current automatically, so what you see usually reflects
your live catalog without you having to do anything.

## Scheduled scans

Atlios rescans your connected stores automatically, so issues stay fresh even on
days nothing changes in your catalog. These run on their own and appear in your
[Activity](/guides/review-job-history) like any other scan.

There are two scheduled passes on every plan:

* **A weekly full scan** re-checks every product, runs catalog-wide checks, and
  refreshes your overall quality scores.
* **A daily diff scan** catches products that changed since the last pass, so new
  issues surface within about a day instead of waiting for the weekly scan.

Scans are controlled backend work. They start on schedule rather than from a
manual action.

## Live product changes

When a product changes in Shopify, such as an edit to its title, price, or
images, Atlios notices the change and re-checks that product shortly after. This
keeps the issue list in step with everyday edits as they happen, in between the
scheduled scans.

## Why an issue might look out of date

Because the catalog and your issues update on slightly different schedules, you
may occasionally see an issue for a product you already fixed. The next live
re-check or scheduled scan clears issues that no longer apply. For more on how
issues open and close, see [Issue lifecycle](/concepts/issue-lifecycle).
