For some reason I keep getting a temporary log in error from the amazon app store application. I've tried clearing data, uninstall/reinstall, and even a fresh download of the app.
Same issue here. I've gone into Amazon and removed all devices but still can't log in with my tablet. I can't get anything downloaded until I can connect to Amazon
Might not be the same issue, but I was having trouble awhile ago and finally figured out that my credit card on file at Amazon had expired. When I updated the card, everything was fine again. Hope this helps.
