Hi @bc_griffin,
You must get loads of emails!
Everyone loves your work.
The notification settings are a little hidden now,
If you click the notification bell, then the settings cog, you should see this page 👇

Or you can click the notifications tab from the dashboard for an alternate view of the notifications, where there is also a settings cog.
They should be the same as pre-migration, but there has been a few quirks.
Hope this helps! 👍
