Some contact fields no longer syncing between TB 102.1.2 and iOS 15.6

[ChrisDriver]

Windows 11
Thunderbird 102.1.2
iOS 15.6 on iPhone 8
BirdieSync 3.2.6.0

I noticed some sync issues since upgrading Thunderbird from 91.x to 102.1.2 and BirdieSync from 3.2.5.3 to 3.2.6.0

Birthdays
Creating a contact in either Thunderbird or iPhone without providing a birth year, causes BirdieSync to not sync the birthday information
Older versions would correctly sync the birthday, providing a placeholder year of birth as 1604
Syncing birthdays with day month and year information works correctly

Contact Photos
Contact photos are no longer synchronised between Thunderbird and iPhone
Removing a contact's photo on the iPhone does not remove the contact's photo from Thunderbird
Removing a contact's photo in Thunderbird, correctly removes the contact's photo on the iPhone
