Lightening to hdmi problem

i have the new 2017 ipad and use a unbranded lightrning to hdmi cable with ubs poer adapter, software says its powered by mirascreen. I use it every day flawlessly. Just plug and play. Now after the ios 11 update i plug it in, it dings like it is recognized then nothing. I should automatically mirror my screen. Anybody have any ideas
