I can't sign in to MS Teams Android app

I can't sign in with all my accounts including company accounts, and my personal account.

I tried reinstalling the app many times but to no avail.

As soon as I type in my email account, all I see is

"Sorry, but we're having trouble signing you in, please try again".

No matter how many times I try, I can't sign in with that same message.

I'm Korean working in Japan and my Google Play Store country setting is Korea, not Japan. Does that matter?

But my personal account should be Korean so that doesn't explain why I can't sign in...

    Hi @黄 仙敬

    Thank you for sharing your situation.

    I'm experiencing a similar issue on my end as well. Microsoft has recently acknowledged a new incident (MO1550821) regarding connectivity issues affecting multiple Microsoft 365 services, including Exchange Online, Microsoft Teams, SharePoint Online, and other services.

    If you are an admin, you can review Microsoft's service health advisory directly through the Microsoft 365 Admin center. If you're an end user without admin permissions, kindly reach out to your Microsoft 365 administrator and ask them to monitor this incident and keep you informed of any relevant updates.

    I hope the issue will be resolved soon.
