Install a new Connect IQ data field to a Garmin Edge Explore 2 as a beta app. In this initial version do not have any references to Application.Storage. Then in subsequent data field updates add Application.Storage and add in some Storage.setValue(key,value) statements in either a foreground or background process. It will fail 100% of the time with unable to invoke symbol. Uninstall the datafield via the IQ store app on the device, then reinstall the datafield via the Connect IQ app on paired phone. The Storage.setValue(key,value) statements will now succeed 100% of the time with no code changes.
