Wifi upload failed – Briefcase Pro - File manager, cloud drive, document & pdf reader and file sharing App Review

I tried to upload a simple text file via wifi/web upload and it failed. There was not even an error message. I tried many times. I'm not new at this. I have other apps like this, so I know it's not me. Please fix.
