After running the anonymization there are no data from other apps (e.g. "Insight") anonymized.
"User Anonymizer for Jira (GDPR)" anonymizes standard Jira data. Data of other apps like "Insight - Asset Management" may not be standard Jira data and will therefore not be anonymized by "User Anonymizer for Jira (GDPR)".
Please contact the support of the provider of the other app. There is an API available that the other app vendor can use. The app vendor can contact us to receive more information.
