Today we released version 1.2.3 of the WHO Data Quality Tool on the DHIS2 App Store. It is available for DHIS2 version 2.29 or higher.
It does not contain any new features, but a bug fix to resolve an issue with the outlier drill down function not functioning on the Analysis page.
See https://jira.dhis2.org/browse/DHIS2-7392 for more information.
You can install the new version through either downloading the zip-file manually from the App Store, or by using the App management app in your instance and then selecting the App store tab.
