Here' maybe labeling might help:
So Default-Old is like THE FIRST PROFILE you get out of the box. You can't delete it.
I don't like that because I have a lot of garbage in that profile, and it has sync issues where not everything syncs instantly (we're talking like 10 minute delays between my Mac and my iPhone).
I just want to delete it and use a different profile to sync my stuff. If you see my past issue, you'd see that I'm asking for this, because I can't even delete the synced data through iCloud: https://orionfeedback.org/d/3566-add-delete-icloud-app-data-in-reset-orion . I would be happy if either this issue or that issue was resolved, since I'm basically having problems with syncing .
