Apple Music for Mac 1.2.4.3 - Cannot Download iTunes Purchases, Automatic Downloads Missing

Apple Music on my MacBook recently lost the ability to download purchases from iTunes. On the iTunes panel, the the albums I have bought appear as "purchased" but they are not in my Library and there is no button to download them. Selecting Account->Check for Available Downloads returns "there are no downloads available". Perhaps strangest of all, the Preferences panel no longer has a check box for Automatic Downloads - see screenshot. I'm running Monterey 12.4. Can anyone help???
