UE5 build iOS Testflight

Hey everyone!

We are using UE 5.4.4 and trying to upload an iOS build of our game to testflight for it to be internally tested.

Whenever we do that and upload it to testflight it shows on our iOS devices but whenever we try to install it we get “Could not install [app name]. The requested app is not available or deosn’t exist.”

All certifactes are right.

Did anyone face this issue? Would really appreciate some help.
