Hello,
I've created a Microsoft Form integrated with a SharePoint list, utilizing lookup columns to implement cascading dropdowns. The form functions correctly for internal users within our organization. However, when I share the form publicly (via the "Anyone with the link can respond" option), external users are unable to see the options in the cascading dropdowns—they appear empty.
Is there a way to configure the form or SharePoint list permissions so that these lookup-based cascading dropdowns are visible and functional for external respondents? Any guidance or workarounds would be greatly appreciated.
Thank you!
