XPS 15 7590 not detecting taps

I just bought a new 7590 and the touchpad doesn't register about one out of every ten taps, when using linux.

I'm seeing the same behavior in ubuntu and fedora.  I don't seem to have any problems with two finger scrolling or moving the pointer.

I had the exact same issue on a 9360 a little while ago that never got resolved.

Ha anything changed since then?  Is there a good way to increase tap sensitivity?

Thank you!
