There are bugs – Telegram Messenger Review

I was using Telegram in Android and saw no bugs. When I switched to iPhone, I faced 2 major bugs. 1. When someone writes me, there is a number on app icon and also on the back button on the chat screen inside the app. I read the messages, but the number is steal there. The only way to remove it is to kill the app and relaunch it. It happens only with some contacts. 2. When I make audio message, big Play button sometimes invisible. Please fix at least first bug and I will change my review to 5 star.
