At times, you may want to send users a reminder to update their app to the app's latest version. In such cases, you can follow the following steps:
1. Create a segment that targets your users with the current App Version (assuming the current app version is 3.9). Save custom segment as "segment_latest_version".
2. Create another segment that targets all your users and exclude the custom segment "segment_latest_version". Save another custom segment as " segment_update_app".
3. You can now send an App Version Update campaign to this custom segment "segment_update_app" and remind users to update the app.
