Customer Support missing in action. File viewer fails in iOS – Microsoft OneDrive Review

One day after over two years of satisfactory performance by OneDrive, a file won’t open. The error message “Sorry, there was a problem opening the viewer” Fine. Things happen. So I begin to seek support. It’s all automated and inapplicable. Pretty sure if this continues, I’ll move everything to Dropbox and abandon OneDrive. Sad, because I liked it okay for a while. But a company like Microsoft should absolutely have a support environment to solve what I must think is a solvable problem.
