An update is available for the Groove app on Windows 10 Desktop and Mobile

This version still has problems. At least it doesn't seem to be losing track of my album collection on my WHS 2011 system as version 3.6.1210.0 did.

However, while two of my PCs can now see the entire collection, a third PC has only added half of the albums, while a fourth (a Surface 3) refuses to add any albums at all, and will only show albums on OneDrive.

It's also not clear to me what the difference is between "Available offline" and "Only on this device". So, for example on one of the PCs that can see the entire collection, it says there are 1,112 albums available offline. These are the albums held on the WHS 2011 system. Yet it also says that there are 123 albums "only on this device". There are no music albums held on the PC's local drives, everything is held on the WHS 2011 system. So where is the number "123" coming from?

So from my perspective, this app is still not yet ready for primetime.

I agree. In fact, I think they should change the name from "Groove" to "Ditch", which is the giant groove in the ground this whole music thing is stuck in since they got rid of Zune.

You allude to one of my major complaints----there is almost zero documentation on how this system works. Is "cloud match" dead? Are we supposed to upload hundreds (thousands) of tracks to OneDrive?

Thanks, I have already submitted feedback, and will continue to raise issues. I want Groove to work, and be a flagship app, but it's got a very long way to go...

BTW, I spoke too soon - this version of Groove is still losing track of my album collection held on my WHS 2011 system, so that bug is still present. Please can you add it to your list of known issues (it wasn't mentioned in your first post). Thanks.

Not only that, but this latest version of Groove running on my Surface 3 refuses to find any local files (i.e. the collection on WHS 2011) at all. And it’s a hit and miss affair on my other systems as well. Groove on my desktop claims my collection has 1,109 albums; on my Yoga 3 Pro, Groove says I have 1,112 albums, and on my ThinkPad 10, Groove says I have just 644 albums.

Addendum 20 August 2015: after 36 hours(!) of adding files, Groove on my ThinkPad 10 now says I have 1,108 albums available offline. So what’s it to be? 1,109, 1,112, or 1,108?

All instances of Groove are looking at exactly the same collection; one might think that they could agree on the correct total of albums. Oh, wait a minute, Groove on the Desktop PC has just lost the index again, and has restarted to index the collection…

Meanwhile, Groove on my Surface 3 resolutely refuses to see the collection at all, and says I have zero albums available offline.

This is not good.

Have to love the wonderful and very informative "Minor fixes and improvements"
