Hello guys, I am trying to understand but I can't understand I am a bit new to these issues. I have been trying to change the bundle id for two days but I couldn't do it. I am looking for it in Apple Developer but it does not allow me to proceed without making a purchase. Is there no way to do this for free? And by the way, unfortunately I do not have a computer. Thank you in advance for your support.
