What is the benefit of linking an existing Azure B2C tenant to my Azure subscription? For billing only?
I have only found a small blurb about it at the end of the Create an Azure AD B2C tenant section.

Hi @Lily-6039
The subscription is required for Support, Billing and to use Custom Policies. If no subscription is linked to Azure AD B2C, the Identity Experience Framework option will be greyed-out as highlighted below:

Without this option, you cannot create and manage Custom Policies.
To link a subscription to an existing Azure AD B2C tenant, you need to:
Switch Directories to the location of your target Azure subscription
Under Marketplace, search for and select 'B2C'
Select Create to link this B2C Tenant to a subscription
Please "Accept the answer" wherever the information provided helps you. This will help us and others in the community as well.
This can not be the answer as 'Identity Experience Framework' is NOT greyed out in my situation. Under the 'Directory + Subscription' pulldown, it still says there is no subscription for the tenant. Also the Linking(from the default tenant(directory), because it is the only place where it shows up) option shows there is no legitimate Azure AD B2C tenant to link..


Somehow between the lines, you have to get your answer from this doc:

@FlorisWeb-0091 · The reason why you are seeing "No eligible B2C Tenants found" is because you already have a subscription linked to your B2C tenant. In B2C tenant, to see if a subscription is linked or not, navigate to Azure AD B2C and check under Overview blade as highlighted below:
Every Azure B2C tenant must be linked to an active Azure subscription to enable communication, support, billing and advanced capabilities such as Custom Policies.
Ah, so you are saying that it is a requirement to link the B2C tenant to a subscription for billing. Am I reading that right?
