Has anyone else had the frustration of an App being rejected, with the comment: "Error is displayed : app not installed". My recent App submission passed tests on all devices with the exception of Kindle Fire 1st generation. As it has passed the test for all other Fire products, Fire Phone, as well as non Amazon Android, I suspect the issue is with Kindle Fire (1st Gen) software and not my App. I am reluctant to spend much more time and effort with this, but if there is a simple answer, please let me know.
