I've had a whole series of unexpected issues... I disabled it, then re-enabled it using my PC instead of my phone, and it seems to work, except when first returned to my PC it asked me to set up authenticator again... but my phone said this would delete the old version. A refresh solved this.
One glitch, Autheticator calls the account 'GMAIL' by default, can the setup be altered to call it BASSCHAT automatically as this will lead to confusion if people don't change the name and a few months down the line don't know that using 'GMAIL' in Authenticator to get back in.
