I have issues with the login in the Power BI iOS app on iPhone. Login on ipad, app.powerbi.com and Power BI Desktop is no problem.
iOS Power BI 17.3
I started PowerBI as a pilot just on my company email. Now the IT dept migrated the domain to Office 365 with Power BI (login with Azure AD sync).
The account I select is marked as Office 365 account. After I click on Sign in a get the error: Singn in error Please try again later.
I already tried to solve the issue by reinstalling the app. Our IT dept doen't support 2 step verification / Microsoft Authenticator at the moment). But I use Microsoft Authenticator for other company accounts. Removing account in the iOS Power BI app is not possible as far as I can see.
