You can disable automatic updates on your device in the iOS "Settings" app. This will prevent your device from automatically updating your copy of Go Button to the latest version. In Settings, tap on "App Store", then under the section "Automatic Downloads" make sure the "App Updates" switch is turned off.
In fact, we recommend anyone who is currently running a show disable "Automatic Updates". Generally it is always a good idea to be running the latest version. But it is safest to wait and manually update Go Button from the App Store app when you are between shows. Better yet, if you have a backup device you can update first, you can verify your show on the new version before updating your production device.
