How Do I Download 3D Models to Use in Substance 3D Viewer beta?

I have subscriptions to the full Adobe CC suite of apps and the full Substance suite. I have the Ps 2025 beta and 3D Substance beta newly installed on a Win 11 laptop (Acer Predator). I'm trying to download Substance 3D Assets (3D models) that I can experiment with in both those programs (Ps beta & 3D Viewer beta). I'm having no luck.

How do I download free/included with my Substance subscription 3D models/assets to my computer to be able to work with them?

I click on Download (in Substance Assets online) and nothing happens. All I see besides that button that does nothing is a box at upper right that says "Subscribe". But I'm already a subscriber and my avatar is also visible up there showing I'm logged in. I'm feeling puzzled and frustrated...

Thanks for any help. I just bought this computer so I could explore features of these two betas - Ps and Substance 3D Viewer and keep them segregated from my production apps.
