Citrix does not currently support propogation of azure tags from a master image 

 The target for support of this use case with Azure Tags is for within the first 6 months of 2021. (Subject to change)

The workaround is to manual tag MCS deployed VDAs or alternatively use Azure Resource Group Policies as follows:

  1. Create Resource Groups which will contain both Master VM and the MCS machines
  2. Use Resource Group Policy to define tags so that all resources created in the RG will get these tags
  3. Provide the Resource Group during Catalog Creation, do not let MCS create Resource Group
