No File Upload to iCloud.com via the Webbrowser with OSX 10.10.4
After upgrading to OSX 10.10.4 I cannot upload any Files to iCloud.com via the Webbrowser. Every File I produced with 10.10.3 I still can upload with no Problems. But every File PDF, JPEG,TIFF I produced with 10.10.4 is not possible to upload? Always get the Message: Uploading File not possible, try again later?
Any Ideas?
iMac with Retina 5K display, OS X Yosemite (10.10.4)
