Windows 10: Groove music playlist won't save song order

I have my music saved in a specific order in a playlist in Groove Music with shuffle turned off. However, recently, I added some new pieces to the playlist again, in a specific order, then left the playlist and re-entered it, only to find that the playlist order had changed for the new set of pieces I had added. I rearranged the pieces back into the order I wanted them in and when I re-entered the playlist, the same thing happened - the pieces had rearranged themselves again.I tried rearranging, playing the pieces and then closing the program, but when I reopened the playlist A, even the p

Adding iTunes playlist(s) to Groove Music

So I have done those steps...it's added all my music again, as before, but the playlists that have synced are the ones I created in Groove myself.

I added a few songs to the Flamenco playlist from the Groove library, which Groove synced from iTunes. All my music is there in the Groove music library except the iTunes playlists.

Your patience and determination astounds me.

 

Music and Playlist problems with Groove Music

Is there a known issue with Groove Music in either the latest build or it's latest update. Over the years I noticed that XBox Music and Groove Music downloaded music in a strange way. If I wanted to make a playlist available offline, it wasn't simply downloading
music from OneDrive into the default music location. It hadn't even preserved the name of the file. Now in the last few days I just noticed a couple problems.

1. I'm starting to see duplicate files. I'm starting to see files I downloaded manually as well as those files in "OneDrive Cache." Before they all just showed up as the song tile. Now some show up as that funny file name.

2. All of the sudden a lot of my songs on playlist are showing as streaming only.

3. Some playlists let me re-order them and some don't.

4. Some songs are now listed under unknown artist instead of the artist for the song, I guess because not both artist and album artist are filled out in the file data.

5. A lot of my playlist are having a problem I once saw in the old XBox Music app. Adding a song to the playlist seems to make the playlist reorder itself.

This is a Lumia 640 on the latest mobile build and all apps completely up to date. I've had no real problems with Groove since I first upgraded to Windows 10 Mobile. I've recently done a master reset. This is a strange issue.

 

WMP Will Not Save Playlist

I have a new computer with Win 10 Home installed. I am trying to use WMP and create some music playlists. When I create a list of songs and try to save them as a playlist I get a pop-up that says: "Windows Media Player encountered a problem while creating or saving the playlist". I have clicked on "Web Help" in the pop-up box and tried all the suggested solutions, but none of them have solved the problem. Can you please help.
