Connection breaks up very often...

I like the preview on my iPad mini and iPhone 6! Really! It is fast and great.
BUT the connection still isn’t stable and robust! It isn’t possible to reconnect within the app once the connection is lost. I have to restart the app every 5 minutes and wait for a new connection in sketch. 5€ is way to much for an app which doesn’t work!
