I'm trying to submit an update for an existing UWP application (ThoroughWorks). I've made several successful updates previously. The only information I'm receiving is the message "A previous submission failed certification.".
I have tried rebuilding and resubmitting many times. I have no information for why this is failing. I don't even know if it's the build or meta-data related. I see no error code. I can't find any details about the failure. All I can guess is that it seems to happen during the pre-processing stage, because I have not been able to see it progress beyond that before reverting back to failure.
During previous submission, I had issues with the version of the Microsoft.NETCore.UniversalWindowsPlatform package, but I've tried several versions without success this time (latest, 6.2.10, 6.1.9). And then, at least, I was given an error code to work with.
I'm using the same build configuration as I was using when I've successfully updated the app previously (release, .net native compilation, optimize code).
