Re: Cross origin frame error after updating to Edge 98+

Yaseenkk Do you have a repro we could look at? Or at least un-censored error messages? What are the two origins (top-level page, and frame)? Did you verify the expected content had loaded into the frame (and was not blocked by Tracking Prevention)?

Generally speaking, nothing should have changed here recently; there is a plan to remove the ability to use document.domain to relax Same-Origin-Policy, but that change won't land until Edge 106: https://docs.microsoft.com/en-us/deployedge/edge-learnmore-origin-keyed-agent-cluster
