So, I finally got some useful info back from Nook.
The issue is in using LETTERBOX in the config.lua. Apparently they no longer allow you to use letterbox, even though our apps have been out on the Nook for 6 months using that mode.
IF I knew it was a Nook device I could change my build.settings with an if/else statement, but since no one at Corona has answered my questions about the system.getInfo(“model”) return values for Nook devices, I cannot really do that.
I’ll just remove letterbox entirely from my config.lua, but this is not an ideal solution as scaling to fit the entire screen looks really bad on some other Android devices.
So, bottom line: do NOT use LETTERBOX mode in your config.lua file for Nook submission [import]uid: 120686 topic_id: 31650 reply_id: 126585[/import]
