2FA was added and activated. But seems like another bug again on security with GA not sure of. If this work using different browser, since i used UCBrowser. I tried activating my GA 2FA. Then log out on eXchange then log in again but still same process was requested. The 3fa i believed..need to check my email and code was sent and same procedure to get through with the eXchange. The 2FA on GA is disregarded. I get in with my acct without any 2FA code from GA.k
