Hi @ben12 and thanks for reaching out,
I know you had mentioned seeing to all the documented changes so apologies if you’ve already reviewed this doc, but could you confirm your custom login has been updated appropriately? That material covers a number of other aspects surrounding custom login and domains. If you’ve already gone through those resources, would you mind sending me your tenant name in a DM? I might be able to see a bit better what’s happening that way.
I’m also linking to our rules in relation to the authorization extension, I don’t see mention of a default rule that gets created automatically what’s the rule name that got created when you installed the extension?
Sorry I don’t have an immediate fix but please review the material, and I’ll be happy to assist further once I know a bit more.
Best,
Colin
