Because WKWebview has CORS problem. So I need to force/change WKWebview to UIwebview. I have changed to UIwebview, but no luck. I think UIwebview still does not work because there is not configuration about UIwebview in imageCache.ts.
I think this solution is temporary. Because it is harmful and a disadvantage to disable CDN Cloudflare on my site. It is support my site speed and security.
On iOS when CDN activated, it successfully get API from original site host/IP. But all image and video requested to CDN IP — and caused the image and video not appear. This is confusing and not happening on Android version.
