Long delay between doorbell ring and connect through appt

I have a Ring doorbell and Chime, I bought it so I could speak to couriers to tell them where to leave a parcel when I’m not able to answer the door.It takes so long to connect from the chime ringing to connecting to the camera to speak to the courier that they have gone before the link is active.I have WiFi 6 with good coverage all over my property, what is causing the delay and is there anything I can do about it?
