ss.dependency "AppLovinSDK", "~> 13.1.0"

The current AppLovin SDK version used here may cause dependency resolution conflicts in client projects that use AppLovin SDK version 13.2.0 or later. Downgrading client projects to use the older version is not feasible as version 13.2.0 introduced a new initialization API and includes important bug fixes.

This is resolved in 4.2.6.

However, using the optimistic operator for the AppLovin dependency might still lead to issues in the future as versions above 13.4.0 won't be supported. The latest AppLovin SDK version is already 13.5.0.
