In-app visual notification of Group invite
Users who are invited into a group but have disabled notifications, will only know that they have a pending invitation via e-mails (and we know that more than 60% of our users and subscribers don't even open our e-mails). I suggest we consider an in-app system to show there's an open invitation (e.g. as an in-app notice that you have a private message via a red dot in your settings mnue, or the burguer menu).
