 * Hi everyone,
 * We want to inform you about a critical update regarding connecting the plugin
   to your store.
 * **What’s changing?**
    - The plugin’s authentication flow has been updated since version 3.5.0 (as 
      of June 2025).
    - The old authentication server (used by versions lower than 3.5.0) will be 
      completely terminated by the end of this year.
 * **What this means for you:**
    - You will no longer be able to connect your store to Facebook (or modify the
      connection) using versions older than 3.5.0.
    - To continue using the plugin, you must update it to the latest version.
 * **Action Required:**
    - Update the plugin to version 3.5.0 or newer as soon as possible.
 * If you have any questions or need help updating the plugin, feel free to reach
   out!
 * Thank you for your attention.
