Fixed issues

This hotfix addresses the following issues:

  • Custom Chart - data not available on Group views.
  • Subscriber improvements for version 11.5.
  • Performance issues related to limitations and groups.

  • Small issues related to limitations and groups, such as broken group member links.
  • Alerts with Group Member conditions cause errors and fail to fire.
  • Issue with increased Memory/CPU consumption.
