AzureDevOps Pipeline 'Classic Editor' not visible when trying to create a pipeline

I am trying to create a Pipeline in AzureDevOps for our Azure Data Factory CI/CD process. I would like to use the 'Classic Editor' to create the pipeline, see image.

However, when I select 'Create Pipeline' I am not given the option to use the Classic Editor, I get the following:

Can someone let me know how go activate the Classic Editor in our Azure DevOps please.

I am not able to see the release tab under pipelines, see image. Do I need additional permissions?

With the 'Release' tab being disabled, can someone let me know how I would view the following screen? Or would this all be built with YAML code?

You can disable creation of classic pipelines by turning on two toggles at either organization level or project level.

To turn them on, navigate to your Organization / Project settings, then under the Pipelines section choose Settings. In the General section, toggle on Disable creation of classic build pipelines and Disable creation of classic release pipelines.

When you turn them on at organization level, it is on for all projects in that organization. If you leave them off, you can choose for which projects you wish to turn them on.
