I'm not going to agree to a 3-day trial period followed by am auto-triggered unless you cancel through the Play Store $40+/yr subscription. Let me try the app first but feel free to remove any of the features that you believe are worth $40+/yr unless I agree to a subscription. I'm not going to agree to yet another subscription that I may forget about due to $life and the app'a relatively small per month sum without knowing that the app offers some worth to me.
