I just upgraded to the iPhone 8 from the 6s last week. The only issue I'm having is that some apps which used to remember me don't seem to any longer. I get logged out of forums whenever I switch away from them and my banking app which is supposed to log me in via the fingerprint scanner pops up a window telling me it has detected changes to my device so I have to enter my password instead. Which setting(s) should I be looking at to get this to stop? I'm tired of logging in every time I want to check out a forum and I'd like to take advantage of the apps which utilize the fingerprint scanner for security.
