Popup & Embedded Forms (one issue and some questions)

Hello

1. I can place the Embedded Form I created in the MailerLite Dashboard but when the form gets filled in, no Success message appears, merely this: https://i.imgur.com/2hQKHr7.jpg Why is this happening?

And, please let me know if I have the following information correct:

2. Pop up forms do not work with the free MailerLite account and WordPress? (I created a pop up form in the MailerLite dashboard, but it does not show up in MailerLite’s WP dashboard. https://i.imgur.com/Av9latG.jpg and https://i.imgur.com/EWt6e6u.jpg Does this mean there is no way to use a Mailerlite form as a pop up in WordPress?

3. There is no way to additionally format an embedded form once it has been dropped into an Elementor page using the shortcode widget?

4. When in the WP MailerLite dashboard if you go to “Create new signup form” and select “Custom Sign Up Form”, there is no way to format the form with my company colours or fonts that I’m using on my website? https://i.imgur.com/2hQKHr7.jpg

Thank you for your assitance.
