I have set up sharing our vault on iCloud Drive with my wife on MacOS successfully: I created an own (not the automatically created that was non shareable) Cryptomator folder in my iCloud drive and shared it via the MacOS standard functionality with my wife. On MacOS there is the possibility to select a folder in the iCloud drive for an existing vault - so the sharing works.
But we also want to access the vault on our iPhones (iOS 14.3 and Cryptomator 1.5.1). There we only have the possibility to access the proposed folder - we can not select an existing vault in another folder.
How can we set the sharing up in iCloud Drive, so that we both can access the vault via our MacOS and our iOS devices?
Thanks in advance for you help
