Take a look at the project-level “regulatory report” (you’ll find it tucked under Project Information). It has a detailed lists of all Issues and Security Hotspots.
Thanks for this! The report you’re looking for was added after 8.9, so you have one more reason to upgrade.
Make sure you upgrade to SonarQube v9.9 LTS soon, not only to benefit from our Best LTS Ever™, but because soon we will systematically ask users to upgrade when they ask questions about earlier versions of SonarQube, which are now considered unsupported.
