I've also had issues with Google Authenticator for 2FA which is why I like to use microsofts version i've had fewer issues with it. Both are not full proof and you're better off using an SMS 2FA.
This app 2FA is great for sites where you doing constant quick transactions, if you're a long term hodler id say use SMS
Thank you my friend, you are another confirm of the shit is this Google work, even Google + it has betray all users, but they are Google, they can do whatever they want...:(((
