Share restrictions not working

Thanks for the reply - my account is the master one and I set up my wife’s share for myself as “read” but I can still delete files on my phone.

What I want to achieve is that both of us can view all our photos but cannot delete them so I set the share on each of our share folders for photos as “read”. I will then download the app on my wife’s phone as well once I know it’s working. Am I doing this right?
