Not able to cancel CapCut Apple subscription

In my Apple Account subscriptions, I have CapCut Pro on a monthly subscription. I want to cancel it, but the cancel button is not working. No matter how many times I click it, it only loads for a few seconds and then does nothing – it doesn't cancel my subscription. I've tried multiple times, and now I'm going to have to pay for yet another month even though I don't want it. Why does Apple and CapCut not allow me to cancel my Pro subscription? Please help.
