Yesterday, all of two hours before the start of the war, I could finally log on! My favorite game is back. After talking to my guild fully half the members said they had similar problems logging on.
I'm glad I can play, and I figured it was only right to say so: bad news travels quickly, but in order to have credibility one has to equally report good news and or resolution.
I do wish in their communication with me that GREE hadn't tried to pin the issue on my phone and owned up to the problem.
"We're sorry you're having a hard time and a bad experience. We are aware of the problem and working hard to resolve the issues," would have been such a better response than what I got. Which was essentially, "You may need to troubleshoot device."
I'm glad to be back (for now) and I hope it last.
