Hey there!
“See all” on the Messages section of your dashboard’s Support tab should show you the full list of all support activity/messages, and there should be a filter to only show those messages that have not been replied to yet.
From this thread it sounds like there may be a bug or some cases where it doesn’t work as intended, in which case we’ll investigate and fix it as soon as we can!
We’re also working on some other improvements that didn’t make it into the first release, such as being able to set a goal, notifications, and in-app replying for creators to respond to supporters.
