No Impressions sent from Synchronizer 1.x and Python SDK 7.x

Issue

When using Synchronizer 1.x version and Python SDK 7.x version, the Python SDK is processing treatments correctly, Synchronizer does not report any errors, but no Impressions are sent to Split cloud.

Answer

As of Python SDK 7.0.0, design changes where made to match the enhancements made to Synchronizer 2.0 version. Thus, when Python SDK 7.x used, the Synchronizer used must be upgraded to 2.x version.
