We tested it before releasing CBSubs 1.0.0, and within an hour or so the sales got tracked. There were no changes regarding this in CBSubs 1.0.1.
Please re-check the Google Analytics code as described in CBSubs 1.0.1 manual paragraph 6.3.5.4 Settings icon -> Integration tab -> GoogleAnalytics sub-tab page 94.
If it still doesn't work, please reply, and we will redo tests next week.
