Cloud Backup down-arrow not showing a drop-down arrow so I can't add new backup sets

The dashboard is showing "Fix Now" against Cloud Backup button, but no down arrow. I want to define a new backup set but cannot get to Manage Backup Sets.

 

Did you click on Fix Now to see if that helps?

If you need to access the backup settings, open the classic 360 interface by clicking on Open beside Device Security,  and click on the Backup pillar. Then you should be able to define a new backup set.
