After using Xcode 13 to build the app, version of Shake SDK (and all other frameworks included in the app) will be set to match the version of the application - that will cause activity history not to be sent with the report.
Current workaround for Xcode 13, until we fix the issue would be to set
manageAppVersionAndBuildNumber = false
in your ExportOptions.plist to block this from happening.
