Hello there! New member here 
I have just setup a sentry instance self-hosted (using pip, not docker, I know docker it’s the recommended way) and created a single superuser. I have, also, created a single Organization via visiting the appropriate url.
When logged out, I visit the URL sentry.mydomain.com and I enter admin’s credentials. The redirected url stays the same (sentry.mydomain.com) but page shows me the No Organization Access page. However, when I enter manually the url sentry.mydomain.com/settings/myorganization/ I can see the dashboard.
Sentry version used 20.10.1. Do I miss something? Is there an option I should set in order to show the dashboard page in the homepage url?
