Can my organisation use Adobe Stock if some users are licensed for Creative Cloud for Business Pro ?

Can unlicensed users in my organisation access Adobe Stock if our licensed users are assigned Creative Cloud for Business Pro Edition?

We're using CC for Teams, and our Anniversary Date ir rolling around. In addition we have an Adobe Stock subscription. You can't assign the Stock subscription in the Admin Console, since it is associated with the organisation. As such, when I invite users but don't assign them licensing they can still access Adobe Stock credits.

On our anniversary date last year we took advantage of the CC for Business promo. Same price (for 1st year) + includes 'unlimited' Adobe Stock with Extended licensing by default. That's a no brainer.

However, when we came to actually use it we found that the unlimited Stock was tied to individual CC for Business assignments. But you also couldn't layer on an individual Adobe Stock subscription to provide Stock access to unlicesed users.

We had to refund and revert to CC for Teams. I would really like to know if anyone has CC for Business and has successfully provided Adobe Stock access to unlicensed users. Or if anyone could spare a few minutes to test this for me.
