app name not updating in TestFlight

tried all sorts of things and lots of recommendations from "ChatGPT" (boo... yeah sure it is going to take all of our jobs by just guessing at wrong answers... we can do that ourselves, haha) which yielded no answer. we are trying to change the app name but it keeps showing the old name in Test Flight. app shows proper name when installed on device from test flight. yes we are changing the "cf bundle display name" ... i did try deleting test flight and re-installing it, and also deleting app and re-installing it from test flight. still shows old name in test flight. this is a branding issue, the client wants to see the new name. how to fix this?
