I have been having a lot of issues with the remote app. Somewhere in mid service my ipad displays "unable to change slide" it will do this a few times and then the app will close.
At the time I am within 15 feet of the router (with a very strong signal) and less than 25 feet from the computer that is running the presentation. There are no other issues with network in this room.
Today after it did this the computer froze up. It seems to be getting worse each week.
