Another case of hiding menu where nobody expects to find it. Not a good idea
Thanks @altmindo for the picture
In new GMail design there’s no Compose button.
There are Chat, Spaces, Meet, Refresh button (yes, separate from the browser), layout selection, language selection, some sort of groups, activity indicator (for email?), Calendar, Keep, Tasks, Contacts. But no space for Compose button.
You can’t write a new email. In an email service. Literally
Thanks @altmindo for reporting this
