I experienced the change that moved the Dropbox folder to "Cloud Storage" and the sidebar link from "Favorites" to "Locations" on my MacBook Pro (2019 16", Intel CPU). However, after migrating to a new Apple Silicon MacBook Pro (same OS version - Sonoma) today, my Dropbox folder is still in "Cloud Storage", but the sidebar link is now under "Favorites", not "Locations".
Does that indicate any problem?
