NEXT button is not working unless logged in

Hey, I’m using plugins free version and the NEXT button is not working unless user is logged in. I see the last few topics are about the same issue, but there is no public fix so I’m making this thread.

WP version: 6.2.2

MultiStep version: 2.7.4 

Error in console:

Uncaught (in promise) Response { type: “basic”, url: “https://my-site/wp-json/contact-form-7/v1/contact-forms/313/feedback/schema”, redirected: false, status: 401, ok: false, statusText: “Unauthorized”, headers: Headers(11), body: ReadableStream, bodyUsed: false }
