(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).
Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can.

Summary of the issue you are facing:
I set up an email account with fastmail and it works fine when I am in the mail app. When I am on the dashboard I dont see any new email in the unread or important widget. When I switch to mail app it pulls the inbox and shows the email. When I switch back to the dashboard the email shows up in the unread widget. It seems like emails are not pulled when I am on the dashboard. Is there a setting that would fix this? I see the same behavior or a self hosted instance with 31.0.9 and on a hosted instance with Hetzner.
