We're removing the embedded contacts feature in Gmail (see our post on the G Suite Updates blog:
https://gsuiteupdates.googleblog.com/2018/08/access-google-contacts.html).
Going forward, G Suite users can access Contacts via their web browser at
contacts.google.com or the app launcher. This will direct them to the new Contacts (a.k.a. Contacts preview) or the classic Contacts Manager, depending on which is enabled for their domain.
If Contacts preview doesn’t yet meet your needs and you’re required to disable access to the classic Contacts Manager, please fill out the form below and we’ll do our best to accommodate this need.
**Please note that this means your users will lose access to Contacts via their browser.**
