I created an Azure AD Multi-tenant app within my own tenant.
When I try and call the Admin consent endpoint from within another tenant, and signing in as another tenant's administrator, I get the error:
AADSTS700016: Application with identifier 'guid' was not found in the directory 'directory-id'. This can happen if the application has not been installed by the administrator of the tenant or consented to by any user in the tenant. You may have sent your authentication request to the wrong tenant.
How can another tenant provision and allow access to my multi-tenant app?
