When signing into Morty with Google, sometimes Google will keep trying to use the wrong account. Here's how to fix that!
Open your default mobile web browsing app (e.g. Chrome or Safari)
Go to google.com
Tap your profile picture in the right corner to open the account menu
Sign into the Google account you used to sign up for Morty
Open Morty, Sign in using Google and choose the correct account!
That's it! 🎉
