IOS9 and Roberts Radio ConnectR App

iOS and iPadOS

Since updating my Iphone 4S to IOS9, my phone can no-longer identify Roberts Stream Radios on my Wireless Network. I have the Roberts Stream 93I, is any other Apple Device users experiencing difficulties connecting to Equipment on your Wireless Networks?
To access the Radio you have to have installed the “ConnectR” App that is produced by Roberts Radio.
I have removed and reinstalled the App however, no joy.
