Log in issues persists on iPad after update

The long list of repeated ‘FulGaz User’ has gone, but I still have the same old issue. Swapping from my (master) account to my wife’s (family) account works fine. Swapping from hers to mine - clicking my name - loads FulGaz User, followed by prompts to log in. Restarting the app then shows me as logged in (my workaround). Quite frustrating.
