My Pokemon go account has reset

Solution 1:

One thing that worked for me is this solution from a support ticket.

1. Either uninstall and reinstall the Pokémon GO app or sign out of your account (Pokémon GO>Main Menu>Settings>Sign Out)
   • NOTE: You may need to sign out of your account twice to ensure proper log out before signing back in with your correct account.
2. Open Pokémon GO and select the Google login method.
3. You will be redirected to the Safari web browser to complete the login process.
4. Review the email address listed in the top right corner of the page. Ensure that the Google account presented is the same email address used when you originally created your Pokémon GO account. If the email address does not match the email address used to create your Pokémon GO account, please sign out of Google and log back in with the appropriate account.
5. Touch the “Allow” button and you will be redirected back to the Pokémon GO app.

Solution 2:

I had the same issue. The way I got it to work was the remove any passwords from my phone, and to delete and redownload the app. This gave me the logon prompt again and asked me to accept the ULA again.
