How do I turn off notifications about "discoveries"?

How do I turn off all notifications about "discoveries"? I have the text and email notifications off, but still, discoveries clog my notifications area. The notifications about how the system has "found" a hint or a temple ordinance for me are particularly annoying: these are ALWAYS already attached/reserved by the time that I look at them, and are a distraction from the area of research that I'm focusing on. It appears that the same hint or ordinance is sent out to a whole bunch of people, so most people I have spoken to are disappointed when they click on these links. I understand that you're trying to encourage people to come and see what's going on, but if the opportunity is ALWAYS gone before the link gets noticed and clicked, then it's going to have exactly the opposite effect: it will reduce engagement to be consistently disappointed like that. Additionally, they clog the notification area, so that when notifications that actually matter it's hard to tell. And you can't get rid of them without actually opening them. If you cannot turn them off, please fix it so they can be. I wish that the Discoveries were moved to the Activities tab, and that all notifications about them were optional. Right now, you cannot turn them off.

Thanks
