Currently, in the list showing whom you’ve Shared your Shared Album a list appears alongside individual radial buttons you can click as your scroll to “check” those buttons you want to Unshare. There SHOULD be a One Click Option that Unshares All.

Having to scroll and unshare per use is fine but the lack of a One Click. Feature makes the user experience tedious. It also quickly becomes a reminder of how much time you’ve wasted this easier to feel more compelled to delete app and wondering what you could have done instead with the time spent for that purpose.
