Maximes' fixes

## Changes
- Bug on tiny baby iOS devices: Fixed. Pretty ugly but works. Will look at doing properly now. This will do for test flight but not for release, code or app store.

- Bugs shown in video: Fixed, email field still accepts anything

- Updated to use SDK 0.9.3.1, latest version. Videos needed to be added to HC 

- Typo fixed
