No media permissions for added group

[miscs]

Hi,

I have the following problem:

• UAM is configured to hide "everything", which works fine
• I create a new post, which is assigned to group A. Save Post, all fine.
• Later I assign group B also to the post. So now group A and group B do have access.

Problem: Group B has access, to the post but unfortunately not to the included media (pictures). Also in the media library Group B has no access the the pictures used in the post.

Any hints how to solve this would be awesome. Thanks!
