Resolution
Citrix recommends using Managed Disks. Un-managed disks have been superseded by managed disks for Azure-hosted MCS catalogs.
You can convert your existing Azure Template VM that has un-managed disks by following the instructions provided in the Microsoft documentation here:

High level steps:
- Sign in to the Azure portal.
- Select the VM from the list of VMs in the portal.
- In the blade for the VM, select "Disks" from the menu.
- At the top of the Disks blade, select "Migrate to managed disks".
- Click "Migrate" to start the process of migrating your disks to managed disks.*
*NOTE: If your VM is in an availability set, there will be a warning on the Migrate to managed disks blade that you need to convert the availability set first. The warning should have a link you can click to convert the availability set. Once the availability set is converted, click "MIgrate".
Problem Cause
Citrix documentation recommends "Use Managed Disks". Un-managed disks have been superseded by managed disks for Azure-hosted MCS catalogs.
Here is some background on the topic of Managed Disks in Azure-based MCS catalogs in this Citrix Blog.
