Captivate 2017 PhoneGap App Not Loading

I have recently created and published several Captivate 2017 projects as Android apps via PhoneGap.  I have updated the phonegapConfig.xml file as recommended and the publish works well, creating the app as requested.  However when the app is installed on an Android phone and launched, the app does not run and the spinning wheel of death appears and that’s all I get.  Where am I going wrong?
