If the issue persists, try closing and reopening the Pokémon GO app:
  • Android: Tap Settings > Apps > Pokémon GO > Force Stop
  • iOS: Double-click the Home button or swipe up from the bar at the bottom of the screen to see your most recently used apps, find the Pokémon GO app, and then swipe up to close the app.

Additional troubleshooting (Android devices & Google accounts only)

  2. Tap the Accounts menu option.
  3. Select your account. If you have multiple Google accounts, select the Google account you used to log into Pokémon GO.
  4. Tap Remove account.

To add the account back to your device:
  1. Open the Settings app on your device.
  2. Tap the Accounts menu option.
