Check if both devices use the identical iCloud profile. Ensure the information was synchronized during the setup process for the new phone.
I own a single apple account and have explored various syncing methods. It’s a difficult app to configure. While it works fine initially, adjustments become problematic once you switch to newer iPhones.
It looks like none of the options are effective for this situation.
Open the settings on your previous device and configure it for a handover to the newer model. On older iOS versions, this option may not be available. Keeping current is wise.
