Problem setting up Guest access

Hi,I am having a problem (probably my lack of understanding) adding myself as a second user to my Ring doorbell.We have set up the doorbell using an email account we use for home automation - lets call it automation@myplace.here. This is set up and working on an iPhone we use as a control device.Now I want to add my own personal email and my own personal iPad as a second device to monitor the same doorbell. And this seems to be more problematic than I think it should be.On our main automation device I have added me (lets say andrew@myplace.here) as a guest user. I received the email and followed the prompts to add my own account here. All good so far. When I log into that account it wants me to go through the Setup Device process all over again which means I need to unmount the doorbell and rescan the barcode and repeat the setup process - that doesn't seem right so I think I am not following the correct process.I would expect that having set up my account via the email generated by the "Add guest" request, it should automatically link to the doorbell device that I have already set up.Or am I missing something really obvious !!!!!!Regards,Andrew
