Sync on Iphone Doesn't open the Camera App

I have Brave on my Windows and Mac computers and all the Chrome Bookmarks are easily imported.
I’ve tried numerous times to sync to my iPad and iPhone running IOS 13.3.1 and when I select the QR code the camera won’t open in the sync app as it does on Youtube help videos.
Does it actually work or is the facility faulty?
I’ve also tried inputting the word paragraph from both devices and it doesn’t recognise them.
Does Sync work and if so what am I doing wrong and why is it soooo clunky.
Thanks Gizzmo
