How to cancel my subscription, when there is no subscription tab in my settings?

That's odd. Try to restart your device. If this doesn't bring Subscriptions back, try to log out and then log in again.

You can also use iTunes on your desktop computer to manage your subscriptions. More details here:

My iPad nor iPhone has subscriptions either. This is very frustating. They make it easy to make the purchase but difficult to cancel it.

My settings don’t have that and can’t find history anywhere

I want to cancel my Netflix subscription
