I have an Azure account with pay as you go subscription. I created Storage account as discribe in following link
https://learn.microsoft.com/en-us/azure/active-directory-b2c/tutorial-customize-ui
But I can not change the Public access level of the container. It always has disabled as attached images.
Can anyone help me to enable this. I spent lot of time on reading docs. But can not find any.
You need to set AllowBlobPublicAccess
to true on your storage accounts. You can do this in the Portal under Configuration for the storage account by setting "Blob public access" to Enabled.
