Hi, I've been noticing your app for a few days and am interested. So, I created a free account, but I can only access it a few times. I get the PIN in my email, but then as soon as I try to enter even a single filter, the page gives me an error. At first, I thought the problem was mine, but then I tried on another computer, but the same thing happened. Before purchasing, I'd like to be sure I can use the service I paid for. Can you explain? Thanks.
