Marriott apparently considers the latter a low, low priority. Of course, one might ask - why is so important to get your new (higher) status right away? All I can tell you from my personal experience is that it is very important. I have PP status through 2/2019 and at least P through 2/2020. Why do I care about getting LT Gold? But I do care. LT Gold is what I have been hoping to see after 8/18. But no, updating LT status is not important to Marriott. They also screwed up the nights. Some people lost their AMEX SPG nights. In my case, I just realized that I lost one night in SPG but two of my LT years are double counted. So now I have decided not to merge my accounts because I fear they will further screw up.

Years ago, right after the IT system merged between UA and Continental, it took 4 days for miles to post. Loyal customers complained. Smisek could not fathom. I remember he asked why people needed to see their miles post right away - but It mattered to their loyal customers. Similarly, Marriott should have upped the priority of getting the merged status right faster. They failed.
