Hi @jesper8W75R
I'm very sorry to hear that you're having trouble.
The popup means you were editing a package that stored in a Fusion team hub in which you don't have access to.
There're many cases would give such popup when editing package. e.g.
1. Editing a public package which stored in fusion team, since you have no access it would give such popup

2. Two users work as collaborator. User A create a package in Fusion and create managed library to a managed folder in which the two users both have access to. User B use the managed library in Fusion then edit the package which store in User A's team hub but he don't have permission to the User A's team hub, then it would give same popup.
If they're not the case, would you mind invite me to your team hub so that i could take a look?
Best Regards,
Alina
