@Rob Miracle I believe the java.lang.IllegalStateException is being thrown from com.ansca.corona.SystemStartupBroadcastReceiver.onReceive based on @beernathan stack trace. So this looks to be something from Corona itself or one of Corona’s Notification plugins, either V1 or V2.
The same stack trace was also reported by @zdmitrynsk on another thread;
