Yahoo mail stuck on "checking for mail"

I think yahoo might be down right now. I sent myself an email to see what would happen. It's in my sent mail but it's still stuck on "checking for mail". It's technically not frozen, the icon is spinning as it's checking.

I also sent a test email to @popowich to see if they were truly sending as it shows in my outbox. Please comment if you got my test email or not.

Is anyone else having a problem?

Nm @popowich now it's stuck on "sending" and keeps spinning. The one I sent to myself is in the sent but not the one to popowich.

I am on my iPhone. I forced the email to close and reopened it and it fixed it.
