[SOLVED] Connection probs after IOS 10.3

I’ve just bought the new ipad and am struggling to get it to work. It will come up now and again and works but then won’t connect next time although my pc shows up. Another problem is when it does come up the sliders don’t work. Other commands do and the meters are responding but moving the sliders does nothing. I also have an iPhone 7 on the latest IOS and this works fine. Do we know if this is being looked at by Steinberg or has anyone raised an official support request?
