Why my form embedded in a Muse website is not appearing on mobile devices?Asked by onetimelord on May 29, 2016 at 11:58 AM
This is a re-post of a comment on Adding a form to Adobe Muse
I'm not sure which embed code you're using, but I would suggest you to try using the iFrame code, here is a guide that will help you with that: Getting-the-form-iFrame-code.
If this does not help, please provide us the link where the form is embedded on, we will investigate what can be causing the issue.
