Access Denied message

Hi Jaehyuk,

After talking more to the support team, it looks like you do not have a Substance license assigned, which explains why you are currenlty a "viewer" and not a "user". 
Can you please reach out to your admin so they can assign you a license?

I can see that material in "My Assets" on the Substance 3D Assets homepage can be downloaded, but why can't some materials in the collection be downloaded? Why does this message appear?

I still can't download them by using the Creative Cloud Desktop app.

Thank you for the screenshots that was useful!
From what I see in your profile dropdown you are currently set as a "viewer" and not a "user", but from what I understand you have a license assigned and should be able to license assets.
Could you please try using the Creatice Cloud Desktop app (in the "stock and marketplace" space, "3D" tab), make sure you select your org profile as well and let me know if it works there?
A user who recently had the same issue did not have it anymore after changing browsers, so that could be a possibility as well

When I clicked that link for the admin console, this message popped up.

I used the dropdown in my profile on the 3D assets. It seems like I have lots of downloads available with my Adobe subscription.

Hi,

Are you logged in with your company profile as explained in this page?

If you are logged in with your org, when did you select it? When you logged in the platform with the full page being dedidacted to the Adobe login, or by using the dropdown in your profile directly on the 3D Assets website?
