Sandisk connect kicks me off wireless

My wife and I both have the app on our iPads. When we go to the gym, she tends to log onto the gym’s wireless and I use the sandisk connect about 30 feet away. It always overrides the gym’s wireless and there seems to be no way to get rid of the wireless login–cannot delete it in settings, and even deleting the app does not get rid of the override. What to do?

in the iPad settings under wifi you may need to forget the network. Tap the i in a circle and select forget network from the list.
