App transfer not available because of testflight

Recently, I would like to transfer an App to another account. However, I could not go on the operation.

In the lastest testflight, I can not find the entrance to stop the testflight testing. I try to make all testflight testing as expired. However, it does not work.


I can not go on my operation to transfer the App. Anyone who has the same problem occurred know how to resolve that? Thanks.
