 ## Known issues
 
-- When using virtual network injection, use caution in making changes to the virtual network and subnet.  Changes may cause the lab VMs to stop working. For example, deleting your virtual network causes all the lab VMs to stop working. We plan to improve this experience in the future, but for now make sure to delete labs before deleting networks.
+- When using virtual network injection, use caution in making changes to the virtual network, subnet, and resources created by Lab Services attached to the subnet. Also, labs using advanced networking must be deleted before deleting the virtual network.
