Adventurers,
Recent changes to the password system have updated the requirements for passwords to make them stronger. The new requirements can often lead to you receiving an error that states:
"There was a problem updating your account. Please try again later. If this problem persists, please contact Customer Support."
The new requirements for passwords mean you may not use:
A password you have used previously
Common passwords like 'password'
Passwords commonly used by many users (ex: lineage)
