First I thought it was a problem with the default templates, then I noticed they looked ok in gmail. And today I got an Auth0 email letting me know of some changes in the logging UI… it has the same problem as my emails.
We’ve detected the issue and our team is working on that. Indeed it seems like such behaviour is only in Outlook. Unfortunately we got to know it after it happened.
Sorry for the inconvenience and we’ll fix it soon so that you get standard-look emails from us in Outlook in the future !
