Your funds are safe onchain when the app has a problem. Try these fixes:

Make sure that your internet connection works. Turn off your VPN.
Mobile: close the app fully, then open it again. Update the app to the newest version.
Web: reload the page. If that does not work, clear the site data for app.legend.trade or use a private window.
Try a different device or browser.

If the problem continues, contact support and tell us your device, app version, and what you see.
