I have two issues with the stats function.
1. On a single-site setup https://raywaldo.com, the plugin seems to work as advertised – EXCEPT that it lost all my prior stats. I was using wo.com stats and it worked fine. When Jetpack was activated, it deactivated the wp stats plugin and dropped all of my previous data. Both JetPack & Dashboard stats only show yesterday (when I installed) and today.
2. On a multi-site setup https://cdntoday.com, everything seems to be fine. The previous stats are available under the JetPack but the dashboard stats module will not display anything. The config works but still nothing. Cleared caches (several times) still nothing.
