My app was getting the error("is not compatible with your device") when download from the App Store. It seems all iPhone models have this problem. But it can be download well for months until two days ago. And there are no other tips from apple.
Recently, I have submit a new version. But got a rejection because of not using in-app-purchase. I don't know whether there are some relationships about this.
And also, I found that some relevance answers in forum. Mostly focused on build architectures setting(e.g. https://developer.apple.com/forums/thread/67488) which was set correctly in my situation.
