 * Hi.
 * In the dev tools console panel there are some warnings about the apiVersion in
   some of your blocks.
 * For example:
 * Block with API version 2 or lower is deprecated since version 6.9. See: [https://developer.wordpress.org/block-editor/reference-guides/block-api/block-api-versions/block-migration-for-iframe-editor-compatibility/](https://developer.wordpress.org/block-editor/reference-guides/block-api/block-api-versions/block-migration-for-iframe-editor-compatibility/)
   Note: The block “ultimate-post/row” is registered with API version 1. This means
   that the post editor may work as a non-iframe editor. Since all editors are planned
   to work as iframes in the future, set the `apiVersion` field to 3 and test the
   block inside the iframe editor.

 * Hi [@lofesa](https://wordpress.org/support/users/lofesa/) ,
 * Thank you for reporting this.
 * Our development team is already working on updating the Row block to API version
   3. The fix will be included in next week’s plugin release.
 * We appreciate your feedback and patience.
