Logging in via Pokemon trainer club vs Google account

My son’s account was set up with trainer club. Tab did a software update overnight that logged him out. Trainer club wouldn't accept password so he selected the Google login option but it wants to create a new character. Will he lose all his progress if we move forward? We restarted the tab but the Pokémon app is still in the midst of picking a new character and doesn't give us the trainer account option.

Solution 1:

Characters and progress are tied to accounts, so if your son wants to hold onto his, he should log in with the Pokemon Trainer Club as before.

If the app isn't doing this even after a restart, the best option is probably to uninstall the app and download it again from the Google Play store. This won't harm his progress.

Solution 2:

Also, pokemon servers are highly unstable at the moment. This doesn't affect google accounts but for those logging in with a pokemon trainer club account the odds are that it's the servers. Try again Later before giving up.
