Adobe PDF Embed API failing to load intake forms on custom site (avangartclinic.com)

Hello Adobe Community,

We are using the Adobe PDF Embed API (Acrobat Services) on our clinic's website to display downloadable patient intake forms directly inside the browser.

Issue Description: The PDF viewer widget fails to render on our site (avangartclinic.com). Instead of displaying the PDF document, the embedded container shows a blank space with a browser console error regarding Client ID domain mismatch.

Environment & Setup:

• Site URL: (avangartclinic.com)

• API: Adobe PDF Embed API (JS SDK)

• Issue: Error: Client ID is not registered for the current domain.

Steps Taken:

1. Generated a new Adobe Developer Console Client ID explicitly mapped to avangartclinic.com.

2. Ensured the site is served strictly over HTTPS.

3. Cleared browser cache and verified that no ad-blockers are intercepting the Adobe SDK script ([https://documentservices.adobe.com/view-sdk/main.js](https://documentservices.adobe.com/view-sdk/main.js)).

Does the PDF Embed API require subdomains (e.g., www) to be registered separately in the Adobe Developer Console Credentials, or is there a propagation delay for newly added domains?

Any feedback or troubleshooting steps would be highly appreciated.

Thank you!
