Hi @sunnyflower navigating around Connect can be a bit complicated. Here is the only way I know if I already replied to someone. You stated before that you view Connect using your phone. If so then first go to one of the discussions, tap where you see 3 lines together, then on the menu that comes up tap on "My Account", then on the next screen scroll down to "My Profile" and on the next screen that appears scroll down and you will see all of your own posts. Perhaps from there you can tell whether you responded to a particular post or not. Hope this helps. 😉 Best, Hank
