There is a bug in the form where you enter the details of a family member you want to invite. The bug results in valid email addresses being rejected when they contain capital letters => the check for a valid email address is wrong.
The error message is misleading and a user can only find out when looking at the HTML source code of the web page.
The form provides three text input fields (at least on the German spotify website) for the details of the family member you want to invite:
When you enter an email address like FirstnameLastname@google.com (of course containing the correct google.com email address), the email address is rejected with the message "Bitte halten sie sich an das vorgegebene Format" (please stick to the specified format - however there is no format specified). When looking at the html code, I saw that email addresses containing capital letters are rejected.
Please fix or at least adapt the error message.

Thanks for reaching out.
I've passed your feedback about this onto Spotify. 🙂
