Hi Esther, I'm really sorry for the inconvenience. You're referring to the Developer Toolkit, and that was a test-only feature in the Beta version of URLI you were using. I put "! TEST FEATURE" next to it in the UI to try and help remind users. I pinned a notice on GitHub last year to try and let users know that this change was coming (the only way I can really communicate with users): https://github.com/sixcious/url-incrementer/issues/17. I'm really sorry for the change, but it was necessary to protect URLI from being abused by bad actors.
