Cross-origin login Safari "No verifier returned from client"

Hey everyone, I apologize for the delay in response. @Enin, @chauhan.vishaal, @mrkevlew, @markmakes, @s.naumenko since you five are the most recent if you could please snag me a HAR file of the broken workflow along with your tenant names and direct message them over to me, I would be happy to dive into what may be occurring here. Please be sure to select “Preserve log” to catch redirects and scrub the file of user passwords before passing them over, thanks in advance!
