Well, bummer. Until now I didn't know the app wasn't official. I have now removed it, changed password and enabled 2FA. Perhaps a HUGE warning on the official site is in order since many, many users are using the app?
I would hope it would be obvious that any official app would be advertised and linked to from the site.
My minimum payout is still halved though. Any chance it can be restored to normal? ID 12114971. If not I may consider opening a new account. Which sucks, because I'd lose the few refs I have.
Have a quick read back to my previous answers and you'll see what you need to do to get back to full rewards. I don't see that opening a new account will help.
