I noticed two weeks ago the TSS showing in my Calendar seemed incorrect. The recommend time for the ride in the Calendar is different than the time if you click on the ride. Sometimes very different. At first I thought it was just the Dynamic Endurance rides but not it appears to be happening for all outdoor rides. The issues is happening across all devices (PC app, web interface, iphone app). I messaged TR last week and have not received a response.
This is a known bug that’s on our list to resolve. 
yeap. my endurance ride says 1 hr, but when i open it, it says 5! that vastly different planning!
