If you are stuck on the continue button, you probably have a Jailbroken device with notifications issue. To fix this, you need to download a tweak called Push Doctor.
1. Open Cydia
2. Go to Sources
3. Add http://cmdshft.ipwn.me/apt/
4. Refresh, and download Push Doctor
5. The file is big, so be patient
6. Once you finish downloading, restart your device
Please let me know if it worked out for you in the comments section below. I will be glad to help too!
