To get started, it's highly recommended to watch this video tutorial first.
You can open the debugger via the debug icon on right side of the view canvas toolbar, or by simply navigating to https://debugger.appgyver.com.
To connect your device with the debugger, you need to go the main app listing and click your email address to open settings. There, you'll find the toggle switch to connect the debugger.
After a few seconds, the connection should be established and you can start debugging your app.
Note that both the computer running debugger and the device(s) running the Preview app must be in the same local network (e.g. same WiFi)!
