[iOS Beta] Not able to join existing or create new Sync on the iOS 17.4 Beta

[hffvld]

Description:

Not able to join existing or create new Sync on the iOS 17.4 Beta.

Steps to Reproduce

1. Use a device with iOS 17.x Beta
2. Install and launch Brave
3. Three-dot menu > Settings
4. Sync > I have a Sync Code > Enable Camera > allow
5. Scan QR from another device > Observe the message Can't sync this device
6. Close the message and select Enter code words
7. Copy and paste the sync phrase from another device > Observe the same error
8. Go back and choose Start a new Sync Chain
9. Choose any of the 2 options > Observe the infinite loading spinner
10. Close and relaunch Brave > Go to the Sync > Observe the screen without an option to delete Sync Chain

Actual result:

1. Not able to join existing or create new Sync on the iOS 17.4 Beta:

• When creating a new Sync Chain, an infinite loading spinner is shown. Closing and relaunching Brave is causing a broken Sync screen without an option to delete the Sync Cnain.
• When joining the existing Sync Chain, both the QR Code and sync phrase are not working, and error message is seen.

2. This issue is not reproducible on iPad Air / iPadOS 16.7.2 or on Android devices.
3. I'm not sure if this issue will be reproducible on the Prod version of iOS/iPadOS. I don't have a test device for it.
