Hi @George Cutrell ,

It has never been quietly deprecated. According to documentation, it has been well known, if you migrate to platform analytics, then it will auto set that you cannot create new reports in the core UI reports. According to this documentation: https://www.servicenow.com/docs/bundle/yokohama-now-intelligence/page/use/par-for-workspace/concept/... it is stated "Once migration is complete, you won't be able to add Core UI report"
