icloud drive switch icon is missing under icloud
I would like to turn on my icloud drive on my iphone 8, but when I go to settings/icloud, the icloud drive switch icon is simply not there. I've searched for answers by googling, but didn't see anyone had the same issue. I have the most updated iOS 14.6, and had reinstall iOS 14.6 again, but that switch icon still didn't show up. Please help!
This is what I see on my iPhone 8:
Below is the normal screen under icloud (this is from a different iphone which doesn't have any issues):
