I could use a little help, the idea is great! So I thought I will test it right away.
As username I used "MJ23" and it said it is still available. Then I put in my phone number. Next I got the key. So everything was great until then. But the username does not work with the key I got. I have screenshots of everything.
It even says now, that the username is still available.
I hope that is just a problem with me and not for everyone ;)
maybe someone can help.
