It seems that the service is bugged in a major way.
I have tried all the suggestions they say you should try at HTC support and they all fail.
I have tried:
New HTC account
Removing Facebook
Re-installing Facebook
Sync to Dropbox
Sync to Google Drive
I even used a third party application...
DO NOT INSTALL IT, it is the worst software ever produced on this planet. Totally automated and it will scan your whole computer weather you like it or not every time you start that piece of s**t. You can't do anything useful with it what so ever.
