I'm developing a Mac app for desktop, the app uses a Webview to load certain urls. Every things works fine, but when I enabled the "Enable App Sandboxing" option and the correct entitlements for the app, the Flash Player Pluging doesn't load in the Webview.
I tried the answer for this question: Flash videos in WebView not working in sandboxed app. but the flash plugin still not working. Also I tried with Clean product option (cmd + shift + alt + k), but still not working.
What need to do to achieve it?, I need to show the Flash Player plugin in the Webview when the App Sandboxing is enabled.
