On my SPG app, I started out with 8 Platinum years, and as soon as I qualified this year (on 50 nights) it moved to 9 years.
On my Marriott app, I have 66 nights so far, and it's showing 0 silver/gold/platinum years. So it's inconsistent between the two. Apparently the latter is a bug, and hasn't been resolved by IT yet. What did you start this year out as?
