If you encounter difficulties logging into the Help Center on your iOS device or when using Safari, it may be due to the 'Prevent cross-site tracking' setting. This setting, enabled by default, blocks certain data preservation during login redirection, which affects the native authentication process.

To resolve this issue:

1. In the desktop Safari browser

1. Go to the Safari button in the upper right-hand corner.
2. Open Preferences > Privacy.
3. Uncheck the checkbox for the Prevent cross-site tracking setting.

2. On mobile iOS devices

1. Go to Settings > Safari.
2. Scroll down to the Privacy & Security section.
3. Toggle the Prevent Cross-Site Tracking setting to off.
