Disney removed the individual resort "IPO" CL function a few years ago and centralized pre-arrival planning with Disney Signature Services:
https://disneyworld.disney.go.com/guest-services/signature-services/
Disney Signature Services is here 7 days a week from 9:00 AM to 5:00 PM Eastern Time. Please call (407) 939-7777 or email us at disney.signature.services@disneyworld.com
DSS is effectively the same thing as the old IPO setup, the CMs just aren't physically at the resort and are disconnected from actual CL resort operations.
Some guests also report outreach directly from AKL CL in the days leading up to check in, but the normal pre-arrival concierge type functions are handled through DSS.
Hope that helps.
