I think for L-SPG Ambassador guests they are still have a hard time sorting out status. Mine has always said Ambassador until 2020 even before I earned it last year. I tried going the 100+ SPG by hitting exactly 100 nights. No one from the Ambassador service could verify if I actually hit 100 nights. In fact, it took several emails back and forth where I received various night totals for my L-SPG nights.
Who knows where I landed for the year. No email congratulating me on earning status for 2020 and I haven’t heard from my ambassador since November.
The new app says Platinum Premier with Ambassador Achiever (!?!) but does not say until 2020.
