I am having the same issue on the same device. I have already attempted the steps above and they did not resolve the issue.
I am not sure if it is relevant, but I am using a custom rom from Android Filehost (aosp_grouper-7.1.2-ota-eng-20170707).
Also I am installing via the Amazon App store as that is where I originally purchased the app.
