I wrapped this inside a media query for phones and that seemed to have corrected the issue.
.popup_outer_wrap:not([class*=" type-inline"]).position-center-center {
left: 15px;
top: 15px;
}
.popup_outer_wrap.popup_full_height {
-webkit-transform: none;
transform: none;
}
I opened a ticket but haven’t received much support so far, just a guy that didn’t seem to read the comment who told me the signature fields are working just fine (they are), they just don’t show up in the email form actions for me anymore.
