I wanted to try it out so I bought a Pro subscription. No way to purchase through iOS so I had to enter my card number. I cancelled renewal and tried to remove my payment method as per usual practice, but I couldn't. Tried to find a way to get support but the send button on their chatbot box was disabled for me (on Safari if that matters). Regardless of the quality of the AI, that experience ticked me off enough to file a "F you" chargeback with my bank.
