Doesn't deserve a single star – OneDrive for Business (replaced by the OneDrive app) Review

As a 25 year IT veteran and Microsoft Partner, I cannot believe this app doesn't work. It simply won't let me log on. Sure I have a phone certificate issued by Microsoft Office 365 and MFA, but that doesn't stop apps like Box and Dropbox from working. How come one of the worlds largest software companies can't get a cloud storage app to work on an iPhone?
