The Hearts system must be removed

I was so excited to get Duolingo again on my new phone but the Hearts system has totally destroyed what made it so effective in the first place. Instead of being able to drill words and phrases I am having difficulty with, which is what helped me better remember them, Im punished by low health and unable to continue for hours at a time (FOUR HOURS just to earn a single amount of health which if its a section Im already having trouble with basically means Ill end up being unable to get even halfway through a lesson). Of course you can renew one bar of health...if you sit through a commercial or spend an absurd amount of gems. This is so disgustingly exploitative and so utterly subverts the initial attraction and purpose of the app that I am deleting it and wont be returning until the Hearts system is removed.
