You can add the Geocaching App features into the Outdoor 8 App and leverage the Outdoor 8 App to a Multi-Outdoor-tool. Geocaching and Outdoor in one App… awesome!
You must have been purchased the Geocaching and the Outdoor 8 app. Open the Geocaching App and press the Unlock button in Info / Apps. This will enable the Geocaching-features in the installed Outdoor 8 app. The amount of available Geocaching features depends on the version of the Outdoor 8 app vs. the Geocaching version. But normally both apps are close together.
The former Geocaching/Outdoor-InApps will be not available anymore.
