Success message on mailchimp opt-in form not showing (Contact Form 7 + Elementor)

Good Day,

I have used Contact Form 7 plugin to embed my Mailchimp opt-in form on my Elementor Page. Now, on testing the form, I don’t get the success message. However, I receive a confirmation email in my email inbox…

please help…I have no coding knowledge…I’m suspicious that could be the issue here.

Best Regards,
