Downloader version 1.1.7 is now live in the Amazon Fire TV Appstore. This version hopefully fixes the last few remaining issues that were preventing the app from not downloading certain files correctly. I’ve actually split the code into a Fire OS 5 and Fire OS 6 version temporarily so that any potential bugs that make it in while I work on Fire TV 3 compatibility don’t affect older devices. (That is what happened with the v1.1.4 update, which broke certain file downloads on older Fire TV models.) There aren’t two listings and you don’t have to do anything special to get the right version. The Fire TV will automatically download the right version from the Amazon Appstore. I’ll merge the code back together in a future update once I’m confident everything is stable.
I’m sorry if having so many updates recently has been annoying. Just as my developer and I work into the night to fix issues and push out an update, we wake up to newly reported issues and get right back into it. That has been our cycle ever since the Fire TV 3 was released. Development costs haven’t been cheap, so if you appreciate the app, please consider donating through its home screen in-app purchase buttons or by supporting me on Patreon.
