We recently upgraded the subscription to use queries because we thought it would give more flexibility creating the dashboards, adjusting the data to show what was needed, but unfortunately it did not change much, the Qase Query Language (QQL) dashboard shows a list just like in the query session or filtering inside qase.io without having the queries upgrade.
For example, on the defects we created a custom field called 'RCA' and another called 'Sprint' so we could filter all the defects we were having with that specific RCA during a sprint, sadly you cannot use two filters on the 'Open defects' so I cannot show the data of the RCA and the Sprint together. If we try to use the Qase Query Language (QQL) dashboard it shows a list, not the number of defects per RCA on the sprint.
