Navigate to the Store page

Wait for the list of stores to load

Notice the extended loading time (can take several seconds or more)

Expected behavior

Additional context
This issue may be due to unoptimized data fetching, lack of pagination, or large store data being returned all at once. It might be useful to review API response time or implement lazy loading or pagination.

Start at the admin panel's Store page and trace how the store list is requested and rendered. Check the API response time and whether the page loads all stores at once; done means the list loads within the stated 1–2 second target without regressions.
