I suggest you just have him install Alby Go app and create an isolated wallet on your Alby hub, he doesn’t need a Alby account for it

I need some help.
I’m trying to connect my son’s Alby wallet to my Alby Hub so he can utilize my LN node’s liquidity.
When he scans the QR code given he gets the error below. Tried it 3 times.
Any help would be appreciated.
Thank you.
