6 digit verification code autofil from sms is disabled?

[AC Question]

Hey all,

So when I first got the phone, download all the apps, and for got some of the passwords, I asked for new ones using the phone (not computer )and they would send it through 2 step verification with the 6 digit codes. I would receive the text message with code and it would automatically fill it in to the app or browser, but now. If I ask for new pass, they would send the sms 6 digits but it would not auto fill like before.

Im wondering if I accidentally disabled something and needs to be enabled again? I really like this feature and would like for it to work again.

Thanks!
