Not sure if this is N5 specific, but considering we're all kindred folk here (and we're one of the few devices with a legit M port), I figured it applies enough to ask here.

I'm getting an "Amazon Appstore: unknown error" prompt when starting Amazon Appstore apps on M on my N5. I've tried all the standbys - including deleting linked devices, uninstalling Appstore and reinstalling appstore, and uninstalling and reinstalling the apps.

I'm having no problems on my N7 with L, so only thing I can guess is that something with Amazon Appstore's DRM is going wonky on M.

I'm aware that M is going to have issues as a developer build, but I just wanted to see if anyone else was having a similar issue so I could stop trying to solve it and start waiting for a fix from Amazon.

Edit: Contacted Amazon about it - they forwarded it to their techs, so hopefully they get on their way to a fix. Someone mentioned having the problem on XDA, so at least I know I'm not alone.
