You will have a problem unless you can modify the app or service to prevent it from checking the certificate it is presented against what it expects. Think of it like this: You order an uber and you are old the vehicle picking you up will be a red Toyota. You go outside and wait but a green ford shows up saying they are your uber. You refuse to accept the ride, based on previously provided knowledge.

Th same thing for the app, you will need to modify the app’s previous knowledge of the certificate, otherwise it will continue to reject the MITM certificate.
