URIs Array seems to have an undocumented limit

[wolfgang_bures]

When I try to play tracks using the "/v1/me/player/play" endpoint I get results where:

- Player shows an emtpy Queue (this is always the case)

- after one of the first few songs one song seems to continue playing

  - progressbar is full, played time and songduration are the same

  - player shows "playing"

  - next song never comes

  - rewind does not work

  - eventually "unable to play this song" pops up

this happens especially with long URIs arrays (about 180 songs)

Is there ANY documentation on a maximum number/size of the URIs array or the total POST command?
