Crash !!!!!

Yesterday I updated Skype and when I tried to make a call, my iphone 6+ crashed with no reason when I tried to use the speakerphone feature. For about 5 minutes, I could not use the phone at all due to Skype app got hanged?

The new design is gloomy and downgraded in a way? Can you bring back old previous bright colored ones because I do not see any design improvement or Skype is now difficult to use and finding features are not simplified?

Simplicity was the best feature but Skype took it away. Please fix these!!!
