ARC Downloads xxx of yyy items - what does it mean?

I’ve never had much success with ARC Downloads - but after a new install of my ROCK-based RoonCore (and consequent need to re-download everything) I’m trying to understand the downloading process.

For reference, I’m downloading about 600 albums to a Pixel 7 Pro (512GB storage) running Android 15. I’m downloading ‘Balanced’ quality.

Like the first time I downloaded content when ARC was newer, the process is clunky and repeatedly says ‘Downloading paused’ for no apparent reason. I’ll probably raise a support ticket for that.

I’m really keen to understand what ARC is telling me when it says (say) ‘167 of 334 items’ (see screenshot).

The smaller number seems slowly to be going up and the larger one is coming down. (At the time I took the screen shot, 475 items had downloaded.) The numbers don’t increase and decrease at the same rate (that is, they don’t add together to the same total as the decrease and increase.)

I’d really just like to know what xxx and yyy are telling me!

Um………number of items u selected to download that have downloaded / total number of items u have selected to download……weird

You would think! But I selected over 600…

Must be a glitch.
