Hello fitorenore,
I just tested it and it works with most themes including the default WordPress themes. It’s difficult for us to find the cause of this issue on your website without disabling other plugins and switching themes.
For now, I would suggest adding below line of code to the “functions.php” file in your active theme:
add_filter( 'mc4wp_form_auto_scroll', '__return_false' );
The above code will disable the “Auto Scrolling” function in our plugin. Please note, this would cause the page to not scroll when the page reloads and your user would need to manually scroll to the form to see the success message.
We are now working on an update that will use browsers default scroll function to handle this in a much better way. While we can’t promise a date when the update would be released, you can keep a track on the progress by going to https://github.com/ibericode/mailchimp-for-wordpress/issues/273.
P.S. I would kindly request you to create a new support request in future as it makes it easier for us to track each issue and the original post creator does not get notifications.
