I am facing an issue where the login link emails are not being received, therefore stopping users from accessing the system. I have checked the logs in monitoring and there are no errors. This behavior is intermittent and I was able to receive the emails up until yesterday. No new changes were applied to any part of the Auth0 settings for a while now. Sometimes the emails are delivered after a huge delay (30 mins).
Any ideas on how to troubleshoot and fix this issue? Thanks.
