Missing the discussion option!

I had a problem with my iPhone and temporarily used an android. I downloaded duo and played duo with that and it allowed me to review discussions after each question. I really miss that feature now that Im back to my iPhone! A lot of people post links and other helpful info there!!! Please make available for iPhone too!!!! ??????
