LinkedIn announced they are making changes to the services they exposed to 3rd parties.
The changes are meant to provide member clarity and control over the use of their data to 3rd parties. As a result LinkedIn has chosen to deprecate certain services.
The Exchange team identified that LinkedIn will no longer support the type of implementation used is this particular package. This means that the package will no longer be available in the Avoka Exchange.
