URL to form redirecting to app on mobile

I have an app which has a few forms publicly accessible by guests to our organization; they are provided a link to a form-perma in their email. When most try to open the link on an iOS mobile device, the device first asks them to download the app - if they choose Continue to mobile site , it routes them to a login screen instead of the public form. Is there a way around this, or just a quirk of the iOS browsers?
