Midi keyboard recognized for Step Time input, but not Real Time Automatic input

Hello,
If anyone can help me with this problem I'd be greatly appreciative.

I have a Yamaha P-80 keyboard connected to my Macbook pro (Monterey 12.6 in case that matters) via a midi to USB connector. I am listening via cabled headphones connected to the computer's 1/8" jack. Musescore version 3.6.2.548020600.

Steps I took
- connect the P-80 to my macbook
-turn on P-80
-open Musescore
-select Step Time, select measure, "N", click on a measure to add a note.

Result: I can add notes and I can hear the notes I'm playing through my headphones. Success!

Next steps I took:
-select Real Time (automatic)
-select a measure
-click N ( if needed)
-play a note on my piano

Expected result: I hear the note and the note is placed on my score
Actual result: I don't hear a sound. No note is placed on the score. :(

However, if I then select View>Piano Keyboard, and click notes on the keyboard then I hear a note and it's placed on the score for the duration of clicks I hold it. This is what I expected from Real Time Automatic input.

It seems that my midi keyboard is recognized correctly for Step Time input, but not for Real Time Automatic.

I tried quitting Musescore and trying again. If I toggle back and forth between input modes it continues to work for Step Time and continues to not work for Real Time Automatic. This suggests to me that it's a problem beyond Musescore just being able to initiate the connection with my midi keyboard.
