adobe PDF Embed API not authorized on mobile devices, but works on Desktop and Organization issue

Hello everyone,

I'm building my portfolio, which is made of a main page containing a right div where an object loads the requested pages.

I'm using the PDF embed API and it's working fine from a PC - I tested it on Chrome, Edge, and Opera - but, when I test it on a mobile device, I get the error saying 'This application domain (my website URL) is not authorized to use the provided PDF Embed API Client ID.

More than that, by logging into the console a message says 'We have detected that your organization is no longer entitled to the following APIs and services that were added to this project - PDF Embed API.', but I am the only person in the organization and I have not applied any change.

Thank you to anyone responding.
