Amazon Mobile Ads iOS SDK - Threading Issues Fixed?

I noticed several months ago that the Amazon Mobile Ads iOS SDK was causing my iOS app to lock up. The errors had to do with the API accessing data on the wrong thread. I was in a rush to get the app published, and I knew I couldn't include the Amazon Mobile Ads SDK if it was going to cause the app to hang, so I removed it. I cannot recreate the errors to post them here, but I noticed that the SDK has not been updated since the time I was getting these errors. My question for Amazon is: did you happen to have threading errors reported by anyone else in the last couple of months, and have they been fixed? If not in the SDK, then maybe on your server's end?

Sample project has same issue.

Probably It means amazon guy doesnt test this SDK.

And no iOS Developper use this ultra buggy SDK in production environment.

I think this SDK is definitely worth using, but I am hoping that this will be fixed.

Does anyone have any idea on how to get Amazon's attention on this? It is an error that has been there for months and is apparently not on their radar at all. iOS takes threading issues very seriously and this API as-is can hang or crash an app. Ross@Amazon, if you can't help, is there a way you could forward this information to someone who can?
