Auth0 passwordless login is via email code having email delays. Are other facing the same issue?

We are using the free version of Auth0 and use the passordless login with code in our application. since we are not paid subscription cannot create ticket I guess. But we are having delays on receiving the login code from Auth0 today. thought it was just a slowdown in the beginning but now its happening to few users login and signup now. the status page shows all green. is anyone else also having the same issue. also anyone from Auth0 aware of it?

could be the mailgun integration that we have with auth0. not sure which one is delay. mailgun status page also is all green.
