This is at least a somewhat comforting answer. My number of years calculated was never right to begin with, but I ended up sitting with 9 years Platinum after merging. I hit Plat Premier in 2018 again and was hoping to see that number roll over to 10 in early January. I was starting to get concerned that it hadn’t. Presumably once this gets done it’ll flip to 10 eventually, which despite being wrong would still get me LTP status (not LTPP - I’m short on nights unfortunately).
