After upgrading to VMware vCenter 9.1, users may experience an issue where the capacity and usage dashboards fail to load or display data within the vSphere UI.
VMware vCenter Server 9.1
MS Edge Browser
A browser locale compatibility issue exists between vCenter 9.1 and Microsoft Edge's default locale handling.
Bypass the defect by manually adjusting the vSphere UI application language preferences explicitly to "English" to restore capacity data visibility.
