I just purchased this game yesterday on PS5 and am experiencing the same issues.
1. All controllers have control of all human golfers. Each user with their own gamepad should be assignable to each playable golfer. I found myself accidentally playing someone else's turn multiple times.
2. Sometimes, one controller has control and the rightful golfer's controller is temporarily disabled. Very buggy.
3. I created 3 different custom golfers under my account for each of my family members to play against with. I found that there is no option to select more than one custom golfer for a co-op round. This is very disappointing as this is one of the main reasons I even play video golf.
