Why do Sonos S2 & SonoPhone apps load a different number of Amazon tracks?

 When I load an Amazon Music Unlimited playlist I created that has 498 tracks, why are a different amount of tracks loaded when using two different apps?  When I use Sonos S2, 400 of 498 tracks are loaded.  When I use SonoPhone all 498 tracks are loaded.

 If I load the 498 track playlist using SonoPhone the queue on Sonos S2 shows all 498 tracks.  Weird!

Since the developers of SonoPhone don’t use this forum as support, and I don’t use SonoPhone myself, my guess is that the S2 (and likely S1) apps can’t read some of the file types. But you’d need to get support from SonosPhone to get a real answer.

Maybe Sonos set the Sonos app to only read 500 tracks?

You could call Sonos support to confirm that giess.

The Sonos mobile app has a number of artificial limits on the items in a list, sometimes 100, 200 or, now, 400. They evidently chose a poor UX framework that cannot handle these things.

Third party apps like Sonophone, or mine, or the desktop apps, don’t have these artificial limits and show the full lists.

Some bizarre responses here.

Agree with ​@controlav, the mobile Sonos apps are shocking for accurately pulling the full number of tracks from Amazon Music playlists.

Previously, I’ve even seen a number of tracks duplicated at the end of the playlist, so although the playlist track number agrees with the expected amount, the loaded queue is actually incorrect.

@MoPac - if you add another couple of tracks to the playlist, does it then load 500?

Mr. T:

 Just tried that with a playlist of 508 tracks.  SonoPhone loads only 500.  Sonos S2 this time loaded 500 tracks, but it did 200 first then after a short delay 300 and finally 500.  Guess the playlist had to be over 500 to get 500.

 Oddly, using S2, a playlist of 482 tracks only loaded 300 in the queue.  200 first then 300.  After swiping out the S2 app then reopening it there was 400 tracks in the queue.  When I load the playlist with the SonoPhone app I get all 482 tracks.

 Looks like Sonos S2 is rounding off to 100 and skipping the last 82 tracks.

 As a test I loaded another playlist with 298 tracks.  Sure enough S2 only loaded 200 tracks.
