Like others reporting here, I should be Platinum Premier but am still stuck on Platinum. I understand people saying you need to wait a while for things to straighten, but whereas an awful lot of those who got unexpectedly bumped up from Gold to Plat have now been sent back down to Gold, I'm still not aware of any reports from people who got unexpected downgrades (PP to Plat) who have had their status corrected to PP. It's been 5 days so I would have expected some DPs from people whose status had been rectified accordingly.
Some people affected by this are those who completed a challenge from MR Gold. I hope that Marriott isn't now going to come out and say that such people only get Platinum in the new scheme because they were actually an unpublished level of 'pseudo Platinum'!
