Discontinuing Advan Patterns with legacy Safegraph POIs?

Hi - I heard from a user that obtains Advan directly (not through dewey) that in February 2025 Advan discontinued the production of the weekly and monthly patterns datasets with legacy usage of Safegraph placekeys. They appear to now be producing Patterns+ which has their new version of a placekey (now called footprint_id) and the Patterns+ data is not linkable to Safegraph Spend, etc. Is Dewey still receiving a version of newly-produced data that has legacy placekeys? Are there any changes to the Advan weekly patterns data that Dewey continues to provide?
