Returns the current EditVersion revision number for the signed-in user's Now Playing queue. This lightweight counter increments whenever any queue mutation occurs on the server, making it ideal for sync checks without transferring tracks or settings. Returns a single integer Value wrapper rather than the full queue payload.
Use this when: you need to poll periodically or before opening the queue to detect remote changes without downloading the full payload. Compare the returned Value against your locally cached EditVersion and call Get Queue only when they differ. Use this as a lightweight sync check on multi-device clients; Get Currently Playing is better when you specifically need playback state rather than any queue edit.
