If you’re still using v201908, now is the time to upgrade to a newer release and take advantage of additional functionality. For example, in v201911 we improved reporting error messages and added the ability to break down reports by CMS Metadata.
When you’re ready to upgrade, check the full release notes to identify any breaking changes, like
ActivityGroupIDs changing from type int to type long in v202005. Then, grab the latest version of your client library and update your code.
As always, don't hesitate to reach out to us on the developer forum with any questions.
