Amazon version does not work

This review relates only to the Amazon version. While the Google Play and iOS (Apple) version running yes, the Amazon version has only problems. Either you get the message that the server in maintenance mode are, or you get a version level Juno in 2014, which then has a broken Vortex area, offers no new units and many other errors.

Especially bad is then also of Support: I have spent on the play money and since then works nothing. Support staff seem to be completely overwhelmed and refer to a standard email to a version that I can install nciht with my Fire HD.
On the request, at least if you get your money back - you get no more answers and the support is now dead.

Conclusion: as long as the issue is not resolved, stay away from the Amazon version!
Since Amazon yes wants to own (quite badly organized) App Store have absolutely and you have no chance without Jail-Break or Side Apps should climb to the Google Android version is here the steer ... although the game is actually very nice ... but just nciht on Amazon.
