I am absolutely, positively sure that we have previously deployed debug builds of our Android app to Live App Tests.
Recently, however, whenever I try to upload a debug build it get the message "Invalid input". When I then upload the release APK from the same Gradle build run, everything works fine, so I am guessing the problem is indeed related to the build being a debug build.
Can anybody confirm that there has been in change in that regard? That debug builds were OK for Live App Tests at some point but are not anymore? Or should I be looking into our build process further?
Needless to say, whatever the actual reason for the rejection, "Invalid input" is not the optimal error message that could be expected in such a case... ;-)
