Maybe combined with flushing cookies and browser cache it may last longer. I see that you are clicking with two faucets simultaneously, so this problem will recur as this is googles protection, not the faucets.
Well, I don't solve as fast as anyone since I want to fill in my 3.5k claims per day to be done easily. Thank you for your help as well.
