MDK: App update failed (BAD_ENCRYPTION_KEY)

[#1]

Greetings fellow developers:

I recently made the switch to newer technologies, adapting our old HAT apps developed in SAP WEB IDE to MDK apps and now using Business Application Studio. All the tutorials in the SAP Developer portal served as a great introduction to MDK but, when I started developing my own Apps now using the back-end Destination I used for my older projects, I started encountering several errors that needed to be fixed. The latest being the one showed in this picture, and for which I found absolutely no information about it online:

Pieces of information that might be useful: It's a MDK App created from the CRUD template pointing to an on-premise backend system via Cloud Connector. Communication between my environment, through the cloud connector and to the on-premise system works perfectly, I am able to retrieve all my data and metadata without any issues. Offline functionality is enabled, my offline store name has already been defined in my service file and the supportBind property has been set to 'true'.

Just to make sure everything is cleared out can you uninstall and reinstall the client on your device and try onboarding to your application again and see if the error persists?

Thanks

Wow I feel silly now but that did the trick. I forgot the #1 rule in IT: Restart, Re-install, try again, and only then ask for help. Thanks a lot Bill!
