Megathread: May 1st outage follow-up

I also lost guild coins when there was the outage, I coundn't complete the last 3 arena battles to get first place in my guild in time. I know it's not too big of a deal, but it's still a loss.
In the last few hours I too experienced the error 3.0 on iOS at least 6 times, luckily I haven't lost anything because of it. Thanks anyway for trying to fix it quickly.
