I really didn't know, but I'm checking my gopogle authenticator and it doesn't give me the option to save it in the cloud through my email, maybe I think I should uninstall and reinstall the app? but I don't dare yet, I prefer to keep saving the QR code to be able to access at any time, however, this type of problem happened to me a long time ago in an exchange, I exposed my entire case, they asked me for KYC with great intensity, I was able to do it and they managed to reset my account and I was able to go back and do everything, from my password to the authenticator, I believe that Betfury in their support can solve that, they have the ability and moral obligation to do so, so that this customer does not get lost, apart from serving him quickly.
There should be either a green or gray cloud icon. If you don't see the cloud sync feature in your app, you probably have an older version installed. In any case, it's just an alternative way to back up your codes, and it's not necessary, especially if you feel comfortable using QR codes as a backup.
By the way, what about Betfury? As far as I know, they were planning some kind of mega BFG event in the second quarter, but there is still no news about it on the website.
