For me the Heroku status page shows 'No known issues', while the Heroku Dashboard and all my Heroku hosted apps do not work.
+1 - has anyone had any luck getting in touch with heroku support?
we sent an email to support@heroku.com as suggested in the docs when unable to login: https://www.heroku.com/policy/support/#:~:text=If%20you%20ar... But nobody has come back to us yet
