Cannot login to Teams on iphone

Hi All,

I am using Teams with a personal Microsoft account (Microsoft 365 family plan). 

I am successfully signed into Teams on my Mac computer and can use if with no problems.

However, I cannot sign into the app with the account on the iphone app. After entering my password or going through Authenticator, I receive a message: 

No Teams orgs yet

Looks like you're not using Teams yet.

Check that you've been invited by the org you're trying to sign in to. You can also set up Teams for your org by selecting Create new account.

I have already searched extensively but couldn't find any solutions that worked. Have uninstalled and reinstalled the app multiple times. I am on am iphone 16 pro with the latest version of ios installed.

Any ideas? Thanks.
