Despite message stating the service will open to international users, there's been no change to this restriction for 6 months and more. Useless IM/social media service until it does. How about only release it to international AppStores only when the service is available internationally? ### 1/5 — Crash *2014-11-07* Always crash on iPhone 6 Plus ### 1/5 — Doesn't work *2014-04-03, version 3.2.0207* Can't even recognize my number.
