My embedded form is not showing on mobile version.

I embedded a donation form onto my website. The form appears just fine on the desktop version but a mobile version nothing shows up except a message that reads, “Access Form Using Safari To complete form in a new tab, please follow the link below. CONTINUE TO FORM“

I’m assuming this has something to do with the caching or something like that but I’m very unfamiliar with this and I would appreciate someone else’s perspective and guidance. Thank you!
