I experienced this on the iOS mobile app this morning, and I’m also getting it in my Chrome browser on a mac.
On the “AI Workouts” / “Train Now” (https://www.trainerroad.com/app/cycling/train-now) page, when you try to click the suggested workouts, nothing happens. In the Javascript console you get
react-dom.production.min.js:101 Uncaught TypeError: Cannot read properties of undefined (reading 'preventDefault')
at onClick (AiSimWorkoutCard.tsx:67:23)
at onClick (Card.tsx:130:50)
