We have found that some dashboards and reports will not load the first time when being pulled up in Internet Explorer. Chrome, Edge, & Firefox work fine but IE does not. However, if we refresh the page sometimes it will load or after multiple refreshes it eventually loads. Clearing the cache did not resolve the issue, and not all dashboards & reports tend to have the issue. From our testing, it seems that the issue is prevalent more often when using chart per metric with multiple items panels.
Release : 3.7
Component : IM Reporting / Admin / Configuration
