I tried to go to billing, there is nothing in there at all. I went to my user profile, and there's a tab "payment options" that says I have no credit card added but doesn't give me the option to add one. There's also a tab "add credits" which lets me type in an amount to add and apparently click "pay now" despite not actually requesting any payment information.
Finally I discovered by clicking around on everything that if I go to "services" there's a message to add a payment card. I click the button to add details and I'm given a prompt to accept terms and conditions and provide... not credit card details but a link to a social profile? Apparently this is some sort of fraud prevention thing? You want to see who I am? I have no idea what this is, but at this point, I'm frustrated with the user experience, don't see any path forward to actually trying the service, and don't trust you with any more information. No paid service I have ever used has asked for a link to a social profile.
I'm really sorry. I wanted so much to try this out and love it, but the experience around actually getting set up to try it is so frustrating and confusing right now that I'm just done.
I hope these are just growing pains that will be worked out because I think the concept here is great. I'll come back some day with an open mind and try again. I wish you nothing but the best in this journey.
