 * As mentioned in previous comments, the first thing to check is that your WordPress
   core is up to date, along with all your plugins. Then, review your cache plugin
   settings, depending on which one you’re using, or try clearing the cache directly
   from your server.

 * Hi! Luckily there’s a quick fix for this without having to edit each post manually.
 * When you set a gallery to “Large” in Gutenberg, WordPress saves that preference
   directly in the block’s markup inside the database, like this:
 *     ```wp-block-code
       <!-- wp:gallery {"linkTo":"none","sizeSlug":"large"} -->
       ```
   
 * So all you need is a find and replace in the database. For that I recommend the
   free plugin **Better Search Replace**. Once installed, go to _Tools → Better 
   Search Replace_ and set it up like this:
    - **Search for:** `"sizeSlug":"large"`
    - **Replace with:** `"sizeSlug":"medium"`
    - **Table:** `wp_posts`
 * Before running it, check the **“Run as dry run”** option to see how many rows
   would be affected without actually changing anything. If everything looks right,
   run it for real.
 * One thing though — **make sure you back up your database first**, either with
   UpdraftPlus or through your hosting panel. It’s a quick step and gives you peace
   of mind.
 * And if you have command-line access to your server, you can also do it with WP-
   CLI:
 * bash
 *     ```wp-block-code
       wp search-replace '"sizeSlug":"large"' '"sizeSlug":"medium"' wp_posts --dry-run
       ```
   
 * Should be sorted in under 5 minutes. Good luck!
