Quite a messy integration... not sure why they don't drop the CitizenM+ programme entirely and fully integrate it into Bonvoy from the start.
I've also received that email to give my consent to share my data but when it ended up in a Google Doc page, I stopped. I can't care less.
I have the CitizenM+ members and Marriott Plat so all I want is to get points when I stay at CitizenMs.Which did not happen yet when I stayed in one a couple of months back so I hope it's all integrated for the points by end of 2025.
