Help Set up of Eufy

Hi everyone
I’m new to door bells with video and new to Eufy.
I’m in Australia :australia:
I just purchased this , was told it was easy to set up but having real,problems…
We are not tech savvy but we’re not stupid people either …so would appreciate any input please?
So we are going through the set up .
When we connect the chime up it connects successfully.
When we go to add the doorbell scan QR code on back of doorbell it then tells us to install the chime package before adding the door bell… but we’ve already done that?
Spent too long on this already …about to give up…any clues please ?
Thanks in advance
