Trying To Update A Samsung Store App - Getting Error "the Signing Key Is Invalid. Please Check The Signing Key Of The Binary"

We are building an update Android apk using Corona SDK - with the Target App Store set to 'Samsung'. We are definitely using the same keystore file that we used to sign the origina

Solution 1:

It turned out that the error was not at our end, it was being caused be a fault on the store itself.
We had to delete the app and upload it again as a new application, at Samsung's suggestion.
