I have an Android app that has incorporated Firebase crash reporting.
When I view the crashes in the console, there's a filter option for the "clusters". It's set to 'open' in the image below.
When set to open, I see all the clusters. When set to closed, I don't see any clusters whatsoever. When and how can a cluster become closed? What does it mean for a cluster to be open or closed? I'm assuming it's a means of marking the issue resolved.
The Open/Closed feature is a way for you the developer to mark a particular issue as "open" or "closed." In other words it allows you to mark a crash as fixed so that you can filter out issues that you have already addressed.
To mark a cluster as closed, click the three dots on the far right of the row that appear when hovering over the row, then click "close cluster."
