Bugfix:
In Sisense settings, you can set a "Web Proxy". E.g. if you want to use "mydomain.com/Path/To/Sisense" instead of "mydomain.com".
In the proxy setting, you can enter either (a) "/Path/To/Sisense" or (b) "https://mydomain.com/Path/To/Sisense".
When you use multi-tenancy, (a) doesn't work for tenants, only (b) works. Please make (a) work.
(Specifically: When I open (a), it redirects to /app/account/mydomain.com/Path/To/Sisense/app/mydomain.com/Path/To/Sisense)
(This came out of a tech support case 00830131.)
