Hello Daniel Camcho,
Thank you for reaching out to Microsoft Support!
For your problem, we conducted a test, but the test results are the same as yours, the team created in the migration state cannot be found in the team, even after the migration state results are the same.
The team can only be found in Azure Groups, and the team can be seen by sending request list all teams. This seems to be an API endpoint issue.
I suggest you open a support ticket with Microsoft Support to get help from the API owner.
Hope this helps.
