I've created a custom registration portal to use with PPSK, but I can't seem to get it to work properly. I exported the example that they have and made some modifications to the HTML and uploaded it. The page looks just like I want it to, but when I hit submit on the form it returns "Login Error" "You must enter either your phone number, email address, or both." This also happens if I export the example and then upload it, but everything works fine if I use the "Customize and preview" option.
