I purchased norton wifi privacy vpn... cant download on my Blu Advance 5.0 Android version 5.1 mobile phone, and cant download on my Galaxy Tab E Android version 6.0.1
Are you seeing some error message when you try to download the app?
How are you trying to get the download? From the Norton website or directly from Google Play Store here? https://play.google.com/store/apps/details?id=com.symantec.securewifi
