Quick guess is your app probably uses an external library and the new access restrictions are blocking it. Read up on the whitelisting changes and see if that might the cause.
When you inspected via the Chome dev tools, did it reveal anything?
I will look into whitelisting and see if that fixes my issue. I don't know how to use the chrome sev tools so I havent tested it out on there.
After doing some research on the whitelist changes I determined that was my issue. I made a change that included:
<gap:plugin name="cordova-plugin-whitelist" source="npm" />
<allow-navigation href="*" />
<access origin="*" />
in the config.xml file and that resolved my issue.
