Sometimes Apple devices lose the log in information and this can happen. When logging in, click on “Change User” then “Add Existing User”, then manually enter in your username (email) and password, do not let your device auto populate that in. Then click Let’s Go and see if that works. If that doesn’t, click on “Forgot Password” and go that route.
If all that fails, reach out to our support team and we can continue troubleshooting from there.
Experience the same issue but don’t see an option to switch to an existing user.
After setting a new password I was able to switch user on iPhone and iPad but don’t see such an option on my MacBook
