Pretty sure that's a hivemind thing. Sadly there has been zero updates to the notification logic since created about 2 years ago

Personally I don't mind this. Notifications are not a "core" feature and having them in Hivemind is convenient, but not required.
In my opinion a new notification system is required and can be built in top of HAF

A lot of users requested this in the past, but should be solved at Hivemind level
