This update guide is only for users of Google Analytics in Jira, who installed the app before February 2021.
In order to access the reporting features in Google Analytics in Jira, you will need to update the configuration.
The reason behind this is that previously, only your property tracking code was stored by Jira Cloud. To display reporting, you will need to configure the app to save both the property tracking code and the view ID of the reporting view.
This is straightforward and is covered in the Configuration - Data Collection guide.
Once you have worked through the the Configuration - Data Collection guide, your app will be fully updated to allow analytics reporting within Jira Cloud.
