Azure Devops Pipeline Job

I am unable to run Parallel job in Devops Pipeline getting “No hosted parallelism has been purchased or granted” error and have filled the form now given in the “Microsoft Forms” .

My main concern is that Azure Credentials generated for me is valid for few hours so will the organization and project created by me will be automatically deleted and if it is Yes than how
would I be able to use pipeline than even if Microsoft allows.

Is this in a playground?

Yes it is in playground

I don’t think Parallel jobs are supported in the KodeKloud playground.

So how can i practice then, any workaround or I will have to raise any request to someone in the customer support.
Basically I wanted to test CI/CD
