Tried to make a screenshot of my Jaguar Jersey after an hours ride, but in the meantime I won a climbing jersey (for a short while). After that, I tried to get the Jaguar Jersey back by putting in the promo code, but that did not work. It worked the first time and once after that, but when I took a U-turn, I never succeeded in getting it back. No valid screenshot for me 
If you’re on the F8 then it’ll count.
