Safe driving tap to speak not unmuting

I constantly use the safe driving screen in meetings.  Yesterday it was working fine, but today it stopped allowing me to unmute when I tap the Tap to Speak circle.  The app was not updated recently (since 2/28), the settings in the phone or Zoom were not changed.  I can unmute using the standard meeting screen.  I followed all the troubleshooting advice - changing app settings, phone permissions, force stopped the app, reinstalled the app.  Nothing seems to have helped.  All the settings are as suggested.  No error messages.

Phone - Samsung Galaxy S23

Zoom app version - 6.3.11.28195
