I used the ipad light setup for the first time on New years and it froze up before the show started. I was able to get it up and running again by disconnecting everything, closing the ap, and shut off and re-started the ipad and my iphone. It then stayed solid for the whole night, but I am concerned about if it will happen like this during a show. I have a job tonight and have installed the latest Cuety ap. Any feedback on how to prevent this from happening would be appreciated.
