Tried this?
"If you fail to log in a certain number of times, your Canon ID account will be locked. Even if it is not due to your actions, it may be locked if there is a suspicion of unauthorized login attempts by a third party. You can unlock your account by resetting your password"
Else leave a review at Appstore/Google play and downgrade to a version that works.
