Thanks for the info the season just ended so i have to check some stuff..

The Silver 1 is based on the rating unfortunately (now determines which division you ended) that api call does not return which bracket you played... asked that the team a few days/week back if they could add that.
Need to investigate if i can pull it from somewhere else. I know there is a player details only showing this and previous season but it a authenticated call.

The ranked rewards are indeed gone because the payout is different will look if i can find it and add it to the report.
