flyovers vids not right

Hi, I’ve recently subscribed to strava and after using the flyover video it creates after each of my runs it was great so see, little dot goes along your route you have just ran aswell as a red line following. Now for whatever reason my flyover vids are still working and being created but there is only a little dot following my route and no red line it’s hard to navigate your route. Anybody know why? It was available on previous runs and even if I go back and view them it’s the same now. Just the dot no red line. If I view any of my followers activity and view there flyover they have there’s all fine. 🤷🏻‍♂️ any help please 🙏
