The new roles system under collaboration tab in creator hub does not have correct permissions for Asset permissions tab (and probably more). Our developers have the role with full asset permissions and they cannot access or upload any assets (models, animations) under the group. Not even in a team test.
Asset permissions should work and grant access to viewing and configuring group assets, including animations, models, decals, audio and other development related assets.
Are you still experiencing the issue?
If so, can you share the user IDs of developers and the Org / Group Id that are experiencing this? That would help us investigate faster.
I am marking this as cannot reproduce. The asset permissions change would most likely have fixed the issue. Please let us know if you encounter it again.
