@tanya53 Sure thing – to delete an exercise, view them from your profile while logged in. There is a trash-can icon that will appear over the thumbnails – https://cl.ly/2T3D0T2y1V0w
Wayne is awesome! 🍪
Re: Why did we change it: Nah, we feel it great to be able to re-submit exercise submissions for the very reasons you mentioned. Unfortunately as we fixed the duplicity bug, it temporarily removed this functionality, something we’re working on restoring in future releases. 👍
