Unable to set partials for a prompt in Enterprise plan

I want to add custom fields on the signup for the universal login flow, like first name, last name and a checkbox for accepting terms and conditions on the signup page.

Configure Additional Signup Fields on the Universal Login Page

Tried the above solution, however when calling the /api/v2/prompts/{prompt}/partials
API, it is showing a 403 error:

{
  "statusCode": 403,
  "error": "Forbidden",
  "message": "This feature is not available for your plan. To create or modify prompt 
   templates, please upgrade your account to a Professional or Enterprise plan.",
  "errorCode": "operation_not_supported"
}

However, in the tenant settings, the subscription is “Enterprise Agreement”.

Hi @bedant,

Welcome to the Auth0 Community!

I have checked the tenants associated with the email address you used to create your Auth0 Community account. I found that you are on the Startup subscription plan.

This is consistent with the error message you shared, in which you received a forbidden error because you need a Professional or Enterprise subscription plan.

Now, could you please confirm if you have another tenant under a different email address?

If so, could you also share your tenant name and email address in a direct message?

After doing so, could you please ping me on this thread?

Thanks,
Rueben
