Watch face in store: https://apps.garmin.com/en-US/apps/4f03053e-9ecd-4721-abca-19ca7445f0fe
Test version of watch face in store (with 10kB reduced memory usage): https://apps.garmin.com/en-US/apps/cda199b4-9b63-47fa-9b3b-b7f1ddb02368
The problem seems to occur only for a store app, after sending new settings from Garmin Connect Mobile on iOS, to a D2 Charlie or Fenix 5X watch. Cases where it works:
- In the simulator
- For other watches
- When sending new settings from Connect IQ Store app instead
- When sending new settings from GCM on Android (at least no reports of crash in this case).
In the log file after crashing it says the error is an unhandled exception with message: Key does not exist in Application Properties
The exception occurs when this code is called from onUpdate() immediately after receiving new settings:
using Application.Properties as applicationProperties;
function clearExportImportStrings()
{
applicationProperties.setValue("EP", "");
applicationProperties.setValue("EF", "");
applicationProperties.setValue("EG", "");
}
And all of those properties are defined in the properties.xml file. Here are my string, properties and settings files:

If I had a D2 Charlie or Fenix 5X watch and an iPhone I could try various things to narrow down what is causing the problem, but unfortunately I don't 
It should be possible to create a new blank watchface with the above strings, properties and settings files to see if they still go wrong then, but I wouldn't be able to test it.
So things I don't know because I can't test them:
- Is it only one property which is not working?
- Is it only one type of property which isn't working (e.g. strings)?
- Is it because they are initialised with a certain value?
- Is it all properties?
- Are those properties that crash working ok before receiving new settings? Currently, they are only first accessed after receiving new settings, but it seems likely they would work ok before, since they work when receiving new settings via the GCIQS app.
If I can provide more information or help in any way, let me know!
