We're dealing with some authentication issues for users across two different tenants using Microsoft 365 apps like Teams, Outlook, Excel, and Forms. Additionally, the Azure portal has been slow and unresponsive. I've checked the health dashboard but didn't find any alerts. Just an update: it seems like the issues have been resolved for us, mainly affecting users in the East US.

I'll let you know if we encounter any issues down here in Australia, but nothing yet!
I haven't had any problems on my end, just checked the Azure portal and everything seems fine over here in New York.
We're actually facing multiple user issues across our organization. We've confirmed three separate cases, but it's not linked to the recent April update. We've got a couple of users still needing help, though.
We're also having some intermittent issues with office.com and other admin portals here in the US West. It’s pretty frustrating!
All good here in the US Midwest. No issues reported at all!
Had similar issues in our New York office around noon EST, but it cleared up in about two hours. No other reports from the Midwest or other areas though.

That's rough. Hopefully, it clears up soon for everyone.
