zoho stream web notifications

zoho stream web notifications

since im locked out of IMAP and cant use my mail app that lets my team collaborate and chat below emails, im trying out the zoho version of this... zoho streams.
On the bottom of an email in the zoho mail web app, i "comment" and mention another user.
They dont get a push web notification, they DO get a mobile iOS notification.
On the web they have to pay attention to the little red notification symbol in web mail to see that anything happened.
Is this the normal behavior? No push notifications for comments?
