I downloaded the app because I wanted to be of service, but I promptly uninstalled it when It wouldn't let me continue unless I typed exactly 10 digits. In my country phone numbers are 8 digits. In some countries they might have more than 10. Requiring exactly 10 digits is beyond ridiculous. Hopefully it's just an oversight on the part of the person that made it. Uninstalled, but willing to try it again if this issue is amended.
