App worked fine until 3/1, (with annoyances like transfer services randomly undergoing maintenance for hours at a time during business hours). The app was updated on 3/1 by PNC. Wasn't able to use it until 3/9 due to a blank white screen displaying after launch, until timing out. I discovered *on my own* that Chrome has to be the default browser *for all apps* for this version to work. No communication from tech support, no explanation for why Chrome is now required. Moving to Bank of America.
