@manton seems like login emails are not getting sent.
@mcg Thanks, I think I have it resolved now... You'll need to try again, let me know if it doesn't go through.
@mcg This appears to be an issue with iCloud email. No emails hosted by Apple are being delivered right now, but others are going through. Hoping it resolves on its own. I reshuffled the settings but that was a red herring.
@manton I think it may be resolved now, I just got an authentication email to my domain, which is hosted by iCloud.
