Well, authentication_failed is message from Google Cloud messaging (GCM), which is Google service and part of google service framework and this is again a part of android OS. This message could be seen on 2.3.X devices and 3.X devices mainly. We know about this problem and working on the solution, but we can not be responsible for changing of google services by any way. What happen: on older android versions have been installed two crucial services C2DM and Android Market; these two been dispatching all google communication (means between device and google services, apps, accounts, etc.), but in June 2012 Google stopped supporting this framework and oriented on GCM and new Play - but they are targeted for 4+ android OS. Now the older devices with C2DM installed has been forced to use GCM and Play, but some applications recognizes f.e. only device version and OS version and do not parse the version of GCM/C2DM, so it easily can happen that the communication between device and google service can be broken somehow. Nobody knows when and how Google is supporting or not the “old style” comlink, so yes, the users can experience this type of error. As mentioned, we are working on it, but it is not quite avast mistake :-/ Thank you for patience!
