Steam Guard mobile authenticator bugged when I tried to enter the code it gave me to activate it on this device. It said there was an error with the code itself. Attempts to request a new SMS code were met with a message saying I had "requested too many SMS codes," which is BS because I had only requested the one. Now, pay attention, this is where it gets crazy. IT ACTIVATED STEAM GUARD, BUT NOT ON MY DEVICE, SO WITHOUT EVER USING IT, I LOST ACCESS TO IT. I nearly lost my account. What a joke.
