Can't add a new family member Homey v2

Since version 2 I can’t add a new family member. It is possible to send the inventation link but when the new family member open it nothing is happening. Just getting the login page. When you login it says there is no homey founf and you should buy one.

I tried so send the link via WhatsApp, email and SMS. I deleted the Inventation and tried again but no succes.

Any ideas?
