Cannot log in – OneDrive for Business (replaced by the OneDrive app) Review

Like other users could not log in to the app, however logging in from a browser is just fine. So I thought by updating the app it would fix my login issue , oh I'm able to login now but none of my files are even there!!! We use office 365 for work and up until a week or so ago I was able to attach my files within an email but now I don't have that capability. defeats the purpose of what this app is meant to do. Please fix !!
