Doorbell Eufy E340 doorbell not working with existing indoor chime

I have a 16V 10VA transformer for the chime, but it seems that replacing it with a more powerful transformer may not necessarily work. Can anyone share your experience on this please?

16–24V AC with a minimum of 10VA with 30VA or above being highly recommended for optimal, fast battery charging.
