Currently, people who use pointing devices that do not have scrollwheels can only see the first 3 items in the channel rewards popout in their entirety. Everything below that is either completely or mostly hidden from them. This is a known issue. This was not always the case. According to another poster, scrollbars used to be there for all streams, now it is hit and mostly miss. There have been multiple instances of this issue that I found posted by others, yet you are apparently ignoring those since they aren't getting enough upvotes, you don't want to admit making a mistake, or something else. Maybe I'll need to look for streamers on Kick to support instead.
