Same issue submitted since first Beta version 12. Have Apple bluetooth and USB keyboards. Tab will not tab from cell to cell or section to section in Excel desktop, or any online form.
Space bar does not scroll pages. Rather, it opens program window to full screen zoom.
Menu bar Bluetooth recognizes keyboard. Pref file can never find it. Monterey is useless without properly functioning keyboard. Tried resetting actions. No luck.
Help appreciated.
