Downloading the freshly-bought album on OSX Apple Music is BROKEN.

I just purchased a new soundtrack album. It downloaded fine on my iPhone, no problems whatsoever.

But downloading it on my MacBook is a hot mess:

• "Download all" button AND the download button on an album cover in my Purchased menu only download a single track and are like "Done!". I was forced to go to Songs menu and download every single of 90 tracks individually.
• Once I was done, I discovered that that metadata is incorrect. "Album artist" only features one of three artists. As a result, some songs in the album are missing that artist's name. AGAIN, no metadata accidents when I downloaded on iPhone.

What is this mess?
