Keynote remote loses connection
I'm an actress, I do a live one woman stage show with over 100 images/videos in keynote. It's a great program, the presenter notes cue the theater's technician when to change the next slide. I use my ipad on stage as a teleprompter to alert me to the next slide coming up if I lose my place in the show. I'm following what appears to be the latest instructions on how to connect the devices. Sometimes it starts out fine but the connection gets lost. These are the latest instructions I'm using: https://support.apple.com/en-us/HT204378 I've tried connecting by creating a network, joining a wifi network, just turning wifi on and not joining any network, bluetooth, etc. Any help would be appreciated! Thanks
