Monitoring
After further testing it appears the issue is related to environments specifically using the USD 4.2.0.39 client side regardless of the server side version. We recommend customers stay on Unified Service Desk client side version 4.2.0.29 or lower until we release a new Live Assist for Dynamics 365 package to resolve the issue. Any customers needing to upgrade to Unified Service Desk client side version 4.2.0.39 should test in a lower environment and contact support if they experience problems
