UPDATE (10/25/12): Last night we pushed v2.9.7 to Google Play which resolves the issues from v2.9.5 and 2.9.6. Knots 3D is now again available on Google Play for download and update.
Last night we pushed out the v2.9.5 update to Google Play which had a bug fix and a minor UI change. Unfortunately, users who upgraded had package signing errors and were unable to update. It turns out that the process used to remove the un-needed permissions and libraries is no longer working and resulted in an invalid apk file. See extensive post and discussion regarding the CoronaSDK bundled permissions here and here.
The Google Play developer console does not allow developers to revert back to a previous version so the only way to fix the above was to release a new version of Knots 3D, v2.9.6, without removing the Corona Bundled permissions. This was released several hours after v2.9.5 last night. After receiving emails and negative reviews regarding the permissions, I have decided to pull Knots 3D completely from Google Play. I understand the concerns over privacy and do not want to alienate those users for which this is an issue. Hopefully we can again figure out how to get the apk package properly built without the default Corona permissions and return Knots 3D to the Google Play store.
Our apologies for the inconvenience and confusion.
