Hey,
So firstly I would like to tell you that I am not going to charge you anything for this as its just a quick fix.
If you can share the source code I could check it up. Are you on an iPV6 network while you tested that video? Or did you just simulate one? I had this same issue and kept explaining Apple but they would not listen.
But its a risk to upload such an app coz it might fail on devices. So a couple of questions I would like to ask you.
1. Are you using any Apple API like, HealthKit, HomeKit, Game center or something like that?
2. Are you using any code that checks for internet connection. Remove that first. Just submit it as is. Normally it works. But if there is any API issue from Apple site then it can be a problem.
So let me give you an example, there is this game that was developed on iPhone using Gamecenter. And everytime we would submit, it would get rejected because of the same set of reasons Apple gave you. It turned out that they did not login to Game Center on the device and the debug message was misleading on the app. So when we put in the correct debug message and removed the internet check code and resubmitted it went through. Please give it a try and let me know.
Regards
Jeet
