Device: Kindle Fire HDX 8.9 (3rd Gen)
I'm implementing the Amazon SDK in one of my HTML5 games. I was checking for the general requirements before starting and I found this documentation describing the app testing process. It says we can test web apps with the Web App Tester app and there is a link to download it. I followed that link and took me to the amazon store to "Get this app". I opened the link using my kindle tablet and I was able to "purchase" the app but the device itself was mentioned as incompatible. I went back to my device settings, synced with any new items and checked the apps list in the "Cloud" section, still the app is not visible there. So indeed, the app is not compatible.
I've tried updating the kindle and also factory resetting it. Issue is still there.
I checked in many different Android devices also and it was also a failed attempt with the same message displaying in the app's store entry. I'm browsing from India. Is there any geographical restriction for this app? Please help.
