iPad Pro 12.0, installed iPadOS, won't stay mounted in finder window

if I use a cable to attach it, so I can set wifi, it shows up in the finder window < new install of OSX 10.15 as well >, but when I unlock it, it disappears.


Can't get it to connect again until I disconnect the wire and reconnect it.

Also, not showing up in the new Music app.



any ideas??

FYI... my iPhone 10 shows fine, using IOS 12.4 on that
