Hi aallppeevvaa9612 ,
Were you experiencing this on mobile?
It seems like the custom position we set is making the close button go outside the screen on phones.

Could you maybe try out this custom CSS and paste it into WordPress' Additional CSS?
@media screen and (max-width: 769px){
div[class*=buttonizer-facebook-messenger-overwrite] span iframe {
left: unset !important;
top: unset !important;
right: 0% !important;
bottom: 0% !important;
}
Please let me know if this was the case and if the CSS worked! 😄
