Basic mobile fixes

Mobile login problems are often solved by updating the app, rebooting the device, switching networks, or clearing app cache where supported.

  • Update the app.

  • Try Wi-Fi and mobile data.

Biometric and device recognition issues

Face ID, fingerprint, device recognition, and remembered login can fail after OS updates, password changes, or app reinstall.
