Either by detecting the event or by simply attaching to the final dialog box “Thank you! Your subscription has been created.” with insertAdjacentHTML, I’d like to attach a simple:
<meta http-equiv="refresh" content="1">
Is it possible to do this with a simple script added under Admin > Customize > Themes > Edit CSS/HTML > Head?
Normally it’s possible to add HTML directly to strings under Admin > Customize > Text, which would be the easiest way to solve this, but HTML is disabled on dialog strings, I’m assuming for XSS protection?
