Thank you for sharing your experience with me. The FP sensor issue resolved when I kept the Magic Keyboard connected to my Mac using the included cable.
I suspect Apple pushed an update and the FP issue resolved.
As for the key travel, I'm looking for an alternative (low-profile) mechanical keyboard. Something similar to Apple's minimal design, but compatible with Mac & PC over Bluetooth.
If you have any suggestions, I'd be great if you share them with me.
