S Pen doesn't work on mobile, AT ALL. Can only use my finger

I have just looked online and have seen forums for this issue since 2019/2020. Why has no one fixed the issue with the S Pen? In the mobile app I cannot use the S Pen at all. Can’t grab a minion or play at all. This is a huge issue for me as I exclusively use the S Pen with my Note phones. I always have. I don’t like fingerprints ruing an otherwise great looking display, so I only use the S Pen. Can someone fix this?
