Since update today, I wasn't automatically sent a code so had to use password. I tried basic function in app & whole phone screen went black & no function keys worked at all so it crashed my phone. After finally getting back on, it had automatically signed me out. Then I wasn't even trying to open the app & I was texted the exact same verification sign-in code again! What is going on? It was automatically prompting me to enter texted code & now it's not.
