Administrator access to Teams lost

Question

Hello,
I created a new team for a validation with my private email address. That worked out pretty well. After problems with my company account I have deleted all entries in the Android App Microsoft Authenticator. If I add my private account to the Authenticator by password, I will also be displayed privately. I have an 8 digit code. My business accounts have a 6-digit code. If I want to log in to my self-created Teams, the user is checked first. I can confirm this successfully with the Authenticator.On the next page I choose the tenant. And teams send me a request for the Authenticator. On my mobile phone I get the message: "Notifications from your business, school or university account cannot be processed ...". If I want to login with code I can only enter 6 digits of my 8 digit code. I can't find a QR Code that I can scan with the Authenticator. Deactivating the Authenticator in my private account will not change anything for teams.
I use teams on Ubuntu, Windows and have tried the web client.

Since it was only a test, deleting the team installation would be a possibility. Deleting my private account is not necessary.

Hi Timo!
Did you forget the password of your personal account?
Can you provide screenshot about detailed error message about this issue?
We recommend you to check if your account’s Teams license has been removed.

Hi Jimmy,

i know that password. With this account I write in this forum. The team still exists. Only I can't log in. I'm the only one with the role of owner in Tenant. The others are members.
It is not allowed to take screenshots of the Microsoft Authenticater.

I start teams on e.g. Ubuntu.

1. enter email (Web)
2. approve registration requests (Web)
3. confirm on mobile phone (mobile)
4. Welcome to teams. Select tenant. Next (Web)
5. confirm login request (Web)

   Something's changed here. There's no more messages on the cell phone.A few days ago the cell phone still reported reported "Notifications from your business, school > or university account can be processed".A few days ago the cell phone still reported reported "Notifications from your business, school or university account can be
   processed". Now I get no message.

6. alternative use check code from mobile app (webapp)
7. only 6 digits are accepted.The code (private mail) in the app has 8 digits (Webapp)

I have three codes in my phone
* Private email (8 digits)
* Company email (6 digits)
* Company Email + Teams Tenants (6 digits)

Private Email + Teams tenant missing

Hi Timo!
Modern authentication is available for every organization that uses Teams, so if users are not able to complete the process, there might be something wrong with your domain or your organization's Office 365 Enterprise account.

Hi Jimmy,

it is my private account. The company that manages this account is microsoft. ;-)

My access is from home office without limits.

If I delete my private account on Microsoft, would the team also disappear?
