A worldwide expiration of an SSL security certificate on May 30th, 2020 affected file synchronization between WKO4 and TrainingPeaks. Since that date, data no longer syncs between the two products.
The SSL security certificate expiration affected many businesses around the world and would require significant resources to fix the problem. In truth, we had scheduled the EOL of WKO4 for the fall of 2020 but, given the requisite investment in resources to fix the issue in WKO4, we are now moving the EOL process forward.
