No bluetooth connection after iOS update
So, after upgrading to iOS 11 my iPhone 6 does no longer connect to the Vio via bluetooth - at all. It appears in the bluetooth menu and also in the Vio app, but says "Connection unsuccessful". And yes, the device is turned on and in range. I have reset the Vio, I have restarted my phone, I have reinstalled the app. No solution there. Considering I have also had issues with connectivity in the past ever since I got the Vio, this is a new level of frustration. Anybody here able to help me out on this? I'd appreciate sone advice, otherwise I'll just have to return it (thanks to two years warranty ).
