Some Chrome extensions by default will slow down the speed of the Reporting tool.

We have found that Last Pass is one of these extensions.  If you have Last Pass installed and find that the Reporting feature is very slow to load and function then disabling this extension should speed up the feature.

If you do not wish to disable or remove Last pass as a Chrome extension then you can use an alternative browser to access intelligentcontract i.e. Edge or Firefox.
