UPDATE: It's the default browser that is causing this problem/issue. Went to Settings and changed the default browser to Chrome and the app works now. No thanks to PNC. They changed something in their system to cause this issue, then continue to ignore their customers. Like every single other review of this mobile app, it is terrible! And PNC deigns to not respond to their customers to address the one problem everyone complains about. I would like to deposit a check, and have wanted to, for three days now. But the app will not display the login page, just a white screen. - cleared cache - nothing, then - rebooted phone - nothing, then - uninstalled app, reinstalled app - nothing I called the branch and they said there was no problems with the app (a joke??)
