OAuth 2 w/Custom Domain returns 400 Invalid RedirectUri Cookie

[zach]

Are these two authentication issues related to the same issue/fix?

Cannot authenticate with Custom Auth Flow - second modal skipped

This started happening within the last hour. My resource is configured with a custom auth flow that first requests an user’s email address, and then secondarily a modal that requests the code (which was emailed to them by our auth provider). Recently in the last hour the 2nd code step modal no longer renders and the UI reports “Auth Success”. [Screenshot 2026-03-25 at 12.17.15 PM] [Screenshot 2026-03-25 at 12.18.31 PM]
