MacOS 10.15 (on a MacBook Pro) Finder connects to (mounts) iOS devices from at least iOS12.1 onwards, but there's no way to save, or otherwise process (e.g. Share), files listed under apps that allow iTunes file sharing. Drag and Drop, Command-C,etc have no effect. Also, there is no way of adding/replacing files.
Has anyone else had this problem and/or found out how to Save?
UPDATE: 10 June 2019, I've now filed a bug report.
UPDATE: 21 June 2019, fixed in MacOS 10.15 Beta 2 (19A487l) and iOS 13.0 Beta 2 (17A5508m)
