New Home Hub will add up to 0 Doorbells...

Reolink just got back to me, just after posting this (of course...).
There has been a fresh update to the Reolink app, since Friday morning (to version 4.53.1)... and this has resolved the problem, whatever that was!
I note that item 6 on the update list is "Reolink Battery Doorbell Experience Enhanced ... during initialization..."

Hello,
I'm new to Reolink... I bought a battery doorbell (by the gate, with no wires available), that connects to my WiFi, and a Chime. The aim is to connect to Home Assistant so that it displays on our panel by the front door.
I then tried to connect it to Home Assistant, but failed... and was informed by Reolink support that I needed to buy a Home Hub to connect to HA.

So I bought a Home Hub. This has set up OK, as far as I can tell.
When I try to add my doorbell, I can see it to pair (it's on the same LAN), but it will not connect.
I get the error:
"Unable to Connect
Up to 0 battery doorbells and low-frequency devices (Sub-1GHz) can connect to the Home Hub."
I'm then required to click "I got it" even though I don't get it...

The same error happens if I scan the QR code.

I've searched for this error, but can't find any help.

Can anyone help, please, as I've now spent a lot of money on doorbell and home hub?

Thanks!
