Hi, We currently have a few Addressables issues we are trying to get fixed. If you are finding that the Localization package is not working in the build please try the following: Update to the latest Unity patch version Update to the latest Addressable Assets package in the package manager. Try disabling code stripping Clean All and then Rebuild Addressables. When Building make sure the Editor is set to the target platform in the Build Settings window. Check Addressables group build and load paths are set. https://forum.unity.com/threads/err...th-localization-package.1182001/#post-7566754 On Windows check that the file path to the asset bundles is not over 260 characters long. This can cause loading issues. Try running the Localization Analyzers (0.11.0-preview). This can be found in the Addressables window. https://docs.unity3d.com/Packages/c...anual/Addressables.html#addressable-analyzers If the above does not work then please file a bug report.
