Hi Karsten,
You might have to wait a few more days to update it. This is because Teams has a caching scheme designed to optimize capacity and performance.
The Teams service caches common user information for up to three days. Some data, such as display name and phone number, can be cached in the client for up to 28 days, and profile photos can be cached for up to 60 days.
For more information, see:
https://docs.microsoft.com/de-de/microsoftteams...
However, if you think this is taking longer than usual, and you have access to the Microsoft 365 admin center, you can try creating a service request to investigate the issue.
Please take a look at the article for the steps:

Thank you very much.
