Access the url of the Canvas page containing an iframe
This has just recently stopped working:
Previously, document.referrer would give the full correct url, something like "https://mobap.instructure.com/courses/20533/pages/testing"
Very recently, it only gives "https://mobap.instructure.com/"
This has broken almost every page and link in every one of my classes. I need to be able to access the full referrer url.
Has Canvas intentionally removed this ability? Or unintentionally? Or is it possible this is something my institution can control?
Is there another way to access the url of the page that is loading my iframe?
