Folders on the home page are currently not sorted alphabetically (as they were previously), but rather are shown in chronological order based on date of creation.
We will update here once we have this addressed!
We have this issue almost 100% fixed up. Currently, your existing folders should be alphabetized, but if you add a new folder, those will not be alphabetized. We are working on a fix for this and will update this post sometime soon when things are taken care of!
