We had send an app to Appstore. It was live. We removed it. After a year we decided to change the name, the name is updating in Appstore web, Invitation email received from Testflight is also new name. But when we tap on [View in TestFlight] in the email or the app name in TestFlight iOS app still shows the old name. We update the app info and all the other places. Different name in Appstore and Testflight app for the updated name.
