weird how is it not working , can you explain more ?? cause I have 2FA enabled at luckygames and all working good
the only thing I noticed is that you need to wait 15 secs to pass to enter the code and not sure if it's a general problem or just me , when I enter the code at the first few seconds it shows wrong code but when I wait half of the circle to pass ( 15 seconds ) all work good
that 15 seconds is probably because of a time difference between your authenticator's and site's server time...try to sync your authenticator, that should fix it

I already did that , and it showed that my mobile is already synced with the servers so not sure why this is happening
also I noticed that it happens with other sites too , but at the same time this isn't happening with the majority of the sites I use
so same device synced to the servers but the problem isn't happening with all the sites
