We have an application that uses the ttn-handler-eu (current handler) and no data has been coming through for the past 5 days.
We have another application using the ttn-handler-us-west that is still working.
Please note that the person that setup our application and programmed our prototype devices is no longer available to help us with this so we are looking for help in this community.
From reading other posts, we understand that if we change the Handler in the existing application, this will delete all of our current devices.
If we recreate the devices in this application, do all of the information stays the same as before?
Network Session Key
App Session Key
If we create a New Application, my understanding is that we would have to reprogram the physical devices with the new Network Session Key and App Session Key.
FYI, we can not get access to these devices as they are out in the field, literally.
My question is, are we able to save these devices as they are still functioning and if so, do we change the handler in the existing application and recreate the devices.
