The updated SDK which was supposed to be drop-in upgrade changed the required version of NewtonsoftJson serializer.
We have a large existing codebase and it's not trivial to update this dependency across the platform.
I'd like to request a version of the SDK using the original dependency version, or a serializer-free version in which a serializer can be injected into the SDK by the consumer.
The latter is the best long term solution IMO.
