I just found a workaround. You can open app.TrainingPeaks.com in safari, then click the “Aa” icon in the URL search bar of safari. Then click “request desktop site.” Then go try to drag and pair the activity onto the intended workout. It’s a little glitchy in that you need to drag it just right. But it will work. Once you successfully drag and drop it, the browser will then glitch out for some reason and take you to some weird Google search result page for the url. From here just click ‘back’ and you will have the normal desktop window asking you if you want to pair the activity. This just worked for me. Good luck!
