While looking at a friend's profile I saw that they had a reading challenge that I also am participating in. I clicked on the challenge hoping to see what they used for the prompts, but it just takes me to my own reading challenge page. The same happens also for challenges I'm not participating in. I would want to see what other users' reading challenges look like instead.

I have been using reading challenges assuming that others could see mine as well, but apparently not. This is on Android
